Definitions related to illumination
This document defines and explains key terms related to illumination:
Illuminance is the amount of light falling on a surface, measured in lux which is equal to one lumen per square meter. Luminance is the luminous intensity emitted per unit area of a light source, measured in candela per square meter. Luminous flux, measured in lumens, is the total perceived power of light emitted by a source in all directions. Luminous intensity is the luminous flux emitted in a given direction within a unit of solid angle, measured in candelas.
Principle of Lighting
This document provides an overview of principles of lighting, including definitions of key photometry terms like luminous flux, luminous intensity, illuminance, and luminance. It also covers the laws of illumination, sources of light like incandescent and fluorescent lamps, glare and its types, and models of color synthesis like the additive and subtractive color models.

This document discusses different models for light, including rays and waves. It explores light traveling in straight lines and being reflected regularly. Light can be modeled as either particles or waves, and both views were debated among early physicists. Reflection, absorption, and transmission of light are also covered, noting no material is perfectly transparent and allowing some light to pass through while reflecting or absorbing the rest.
02 light and optics
Light can travel through space in straight lines and comes in different forms, including visible light. There are various ways that light can be produced, including incandescence from heated objects, electric discharge through gases, and chemiluminescence from chemical reactions. Lasers produce coherent electromagnetic waves of the same wavelength and phase which travel in parallel, and are used in applications like manufacturing, astronomy, and entertainment due to their precision and focus.
Ices chapter 8 - illumination engineering
This document discusses illumination engineering and provides definitions and formulas for key terms. It describes:
1. The electromagnetic spectrum and visible light spectrum.
2. Terms like luminous intensity, luminous flux, illuminance, luminous exitance, and luminance and their definitions and relationships.
3. How to calculate illuminance on surfaces using the inverse square law and other formulas, accounting for factors like source intensity, distance, and angle to the surface.
4. Intensity distribution curves and how they illustrate light output as a function of angle.
5. The zonal cavity method for lighting layout and design, which divides a room into cavities and calculates light levels based on factors like room dimensions
Laser
Lasers work by stimulating the emission of photons from excited atoms or molecules in an active medium placed within an optical cavity formed by mirrors. When photons emitted through stimulated emission are reflected multiple times within the cavity, they cause additional atoms to emit photons coherently, producing a very intense and directional beam of highly monochromatic light. Lasers have applications in welding, cutting, holography, medicine, and more due to their unique properties of coherence, directionality, intensity, and monochromaticity.
What is the light spectrum of different visible light sources
What is the light spectrum of different visible light sources ?
The visible spectrum is the portion of the electromagnetic spectrum, Visible light comprises only a tiny fraction of the entire electromagnetic radiation spectrum, yet it contains the only region of frequencies to which the rods and cones of the human eye will respond. The wavelengths that humans are typically able to visualize lie in a very narrow range between approximately 400 and 700 nanometers.In terms of frequency, this corresponds to a band in the vicinity of 400–790 THz. Humans can observe and respond to stimuli created by visible light because the eyes contain specialized nerve endings that are sensitive to this range of frequencies. However, the remainder of the electromagnetic spectrum is invisible. These boundaries are not sharply defined and may vary per individual.Under optimal conditions these limits of human perception can extend to 310 nm (UV) and 1100 nm.

Lumens & color rendering index
The document defines and provides examples for the terms lumens and color rendering index (CRI). Lumens is a measure of the total amount of visible light emitted by a source. It is related to candela, with 1 lumen equaling 1 candela steradian of light. CRI is a scale from 0-100 that indicates how accurately a light source renders color compared to a reference source, with higher numbers indicating better color rendering ability. Light sources with a CRI of 85-90 are considered good, and 90 or higher is excellent for color-critical tasks. CRI is independent of color temperature.
Basic principles of light control
This document discusses the basic principles of light control, including reflection, refraction, diffusion, and absorption. It defines light and its key characteristics such as traveling in straight lines and bouncing off polished surfaces. The four basic principles of light control are then explained in more detail: reflection occurs when light bounces off a surface; refraction is when light changes speed and bends when passing through different mediums; diffusion is when light scatters in many directions from a rough surface; and absorption is when light transfers its energy to the surface it strikes. Specific laws and types of each principle are also outlined.
Luminance and Illuminance
Luminance describes the amount of light emitted from or reflected by a surface, measured in candela per square meter. It relates to the light perceived by the human eye. Luminous flux is a measure of the total quantity of visible light emitted by a source across all directions, measured in lumens. Luminous intensity refers to the directional emission of visible light from a source per unit solid angle, measured in candelas. Illuminance describes the amount of light falling on a surface area and is measured in lux, relating to human perception of brightness, though brightness specifically refers to visual sensations rather than light measurements.

Luminance
The document discusses key lighting concepts such as luminous flux, luminous intensity, luminance, and illuminance. It provides definitions and units for each term. Luminous flux is a measure of total light emitted and is measured in lumens. Luminous intensity refers to the directional emission of light over solid angle and is measured in candelas. Luminance describes the amount of light passing through or emitted from an area within a solid angle, with units of candelas per square meter. Illuminance refers to the total luminous flux incident on a surface per unit area.
Nature of light (2)
Light exhibits properties of both waves and particles. The electromagnetic spectrum ranges from radio waves to gamma rays and includes visible light. Light sources can be incandescent, producing light from heat, or luminescent, producing "cold light" through other means. Objects are either luminous sources of light or illuminated objects that reflect light. Illuminated objects can be opaque, blocking light, translucent, scattering light, or transparent, readily transmitting light.
Bubble power (Sonofusion)
This document presents information on bubble power, a proposed method of nuclear fusion. Bubble power aims to use sound waves to implode bubbles of deuterium gas and cause fusion. If successful, it could provide cheap, clean, and limitless energy. However, developing the technology into a viable power plant faces challenges of scale and the need for more advanced apparatus. Evidence of fusion is assessed through measuring tritium production and detecting neutron emissions. The presentation of bubble power concludes that if these challenges can be overcome, it may revolutionize energy production.
Chap16 Light
The document discusses fundamentals of light, including:
1) Light comes from sources like the sun, light bulbs, and other luminous sources that emit light directly, while non-luminous sources like the moon reflect light and appear illuminated.
2) The amount of light emitted from a source is called luminous flux, while the amount of light falling on a surface is called illuminance, which follows an inverse-square relationship with distance from the light source.
3) Models like the ray model of light describe light traveling in straight lines from sources, and can be used to calculate illuminance on surfaces from point light sources.

- Luminous intensity measures the amount of light emitted in a given direction, measured in candelas.
- Illuminance is the amount of luminous flux received per unit area, measured in lux.

Light
Light travels extremely fast at around 300,000 km/s. It travels in straight lines and we see objects because they reflect light into our eyes. There are two types of reflections - clear reflections from smooth surfaces and diffuse reflections from rough surfaces which scatter light in different directions. White light is made up of all the colors of the rainbow, and objects appear a certain color because they reflect only certain wavelengths of light while absorbing others.
Transfer of heat energy
This presentation describes the processes affecting the movement of insolation of energy through the atmosphere and how energy from the Sun is absorbed by the Earth.
Introduction to laser
Laser stands for "Light Amplification by Stimulated Emission of Radiation." Lasers emit a powerful, monochromatic, collimated beam of light that is coherent in nature. Lasers have several key characteristics that distinguish them from ordinary light sources: (1) They are highly directional with an angular spread of 1mm/m compared to 1m/m for ordinary light; (2) They have high intensity due to their directionality focusing the beam; and (3) They are highly monochromatic and coherent, with wave trains of the same frequency that are in phase. The first working laser was demonstrated in 1960 by Dr. Theodore Maiman using a ruby crystal.
Waveinteractions fp
The document discusses different types of wave interactions including reflection, scattering, refraction, diffraction, absorption, and interference. Reflection causes waves to bounce back at the same angle they hit an object. Scattering is a type of reflection where waves reflect in many directions after colliding with matter. Refraction causes waves to bend when moving between materials with different propagation speeds. Diffraction occurs when waves bend around barriers or through openings. Absorption transfers energy from waves to objects. Interference involves overlapping waves that can either constructively or destructively combine by increasing or decreasing amplitude.
Light & Reflection
Light travels in straight lines called photons at a fixed speed of 299,792,458 meters per second in a vacuum. Reflection occurs when light hits a surface and bounces off, either regularly like a mirror or diffusely, scattering the light. A shadow is the dark area behind an object that blocks light from directly reaching a surface, forming a two-dimensional silhouette of the object.
Enhancement of superconductivity mediated by antiferromagnetic squeezed magnons
This document discusses how antiferromagnetic magnons can enhance superconductivity by mediating attractive interactions between electrons. It explains that while phonons typically mediate superconductivity, magnons from a magnetic material can also induce electron pairing. The key points are that antiferromagnetic magnons have a squeezed ground state with large net spins on each sublattice, and coupling electrons to only one of these sublattices results in a dramatically amplified electron interaction strength and higher critical temperature for superconductivity.

Common modulation techniques include amplitude shift keying, frequency shift keying, and phase shift keying. More advanced techniques like orthogonal frequency-division multiplexing divide the channel into sub-channels and use modulation such as BPSK, QPSK, and QAM to send data in parallel across sub-channels. Higher order QAM encodings use amplitude and phase to represent more bits per symbol.

Basics of radiation and production of x rays
Electromagnetic radiation, including x-rays, is produced when electrons are accelerated and decelerate, such as when they collide with the target material in an x-ray tube. In an x-ray tube, a stream of electrons is emitted from a heated cathode and accelerated toward the anode. When the electrons collide with the anode, they cause the emission of x-rays. This results in a spectrum of x-rays known as bremsstrahlung radiation. Some electrons may also eject inner shell electrons from the anode atoms, producing characteristic x-ray lines. Modern x-ray tubes use a rotating anode to dissipate heat and allow higher outputs.
Infrared (IR) Spectroscopy
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with the matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms.
Spectroscopy
Spectroscopy is the study of the interaction between electromagnetic radiation and matter. A spectrometer is used to measure the presence of compounds in a molecule by analyzing the spectrum produced when matter interacts with different wavelengths of light. Absorption spectroscopy involves matter absorbing radiation and undergoing an electronic transition to a higher energy state. UV/visible spectroscopy uses this technique to study electronic transitions in atoms and molecules in the ultraviolet and visible light ranges.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

03 waves and er day 3
- 1. PHYSICAL SCIENCE Waves and Electromagnetic Radiation
- 2. Bell Ringer 1.)The higher the ________ the more energy is in the wave. 2.) In ___________ waves, the medium vibrates at right angles to the direction of wave travel 3.)Wavelengths of the ER spectrum span from the size of a _______ field to sizes just a little bit larger than an _____
- 3. Objectives ForToday: •Today we are: •Building an understanding of the electromagnetic spectrum •Defining the relationship between wave AMPLITUDE and wave ENERGY
- 4. Agenda/Announcements! •Bell Ringer •Electromagnetic Radiation and the light spectrum •Build wave generator •Finish work pages from yesterday •HOMEWORK: Correction:Worksheets are due TOMORROW.
- 6. Electromagnetic Spectrum © 2000 Microsoft Clip Gallery
- 7. Electromagnetic Spectrum •Visible Spectrum – Light we can see •Roy G. Biv – Acronym for Red, Orange,Yellow, Green, Blue, Indigo, &Violet. •Largest to SmallestWavelength.
- 8. Modulating RadioWaves •Modulation - variation of amplitude or frequency when waves are broadcast •AM – amplitude modulation • Carries audio forT.V. Broadcasts •Longer wavelength so can bend around hills •FM – frequency modulation •Carries video forT.V. Broadcasts © 2000 Microsoft Clip Gallery
- 9. ShortWavelength Microwave •Invisible Spectrum (Cont.) •Infrared Rays •Def – Light rays with longer wavelength than red light. •Uses: Cooking, Medicine,T.V. remote controls
- 10. Animals that can sense infra red •Many vipers and beetles can sense infra-red rays.
- 11. Electromagnetic Spectrum •Invisible spectrum (cont.). •Ultraviolet rays. •Def. – EM waves with frequencies slightly higher than visible light •Uses: food processing & hospitals to kill germs’ cells •Helps your body use vitamin D.
- 12. The Mantis Shrimp – Different spectra • Watch video
- 13. Electromagnetic Spectrum •Invisible Spectrum (Cont.) •X-Rays • Def. - EM waves that are shorter than UV rays. • Uses: Medicine – Bones absorb x-rays; soft tissue does not. • Lead absorbs X-rays.
- 14. Electromagnetic Spectrum •Invisible spectrum (cont.) •Gamma rays •Def. Highest frequency EM waves; Shortest wavelength. They come from outer space. •Uses: cancer treatment.
- 15. LIGHT: Refraction of Light •Refraction – Bending of light due to a change in speed. •Index of Refraction – Amount by which a material refracts light. •Prisms – Glass that bends light. Different frequencies are bent different amounts & light is broken out into different colors.
- 17. OrderingActivity Who was following along? Order the students by wavelength.
- 18. AMPLITUDE vs. ENERGY •Slinky – try making the amplitude twice as large...3 times as large….What do you notice?
- 19. AMPLITUDE vs. ENERGY •SQUARED relationship. •IMPORTANT!What does this mean?
- 20. Wave Generator •Each group will add 10 straws to the wave generator. When finished, these will be used for review on Friday •EACH STRAW NEEDS: •A paperclip on EACH end •To be centered on the tape (IMPORTANT!) •To be evenly spaced (about 1cm in between straws!)
- 21. Wave Generator •Each group will add 10 straws to the wave generator. When finished, these will be used for review on Friday •EACHTABLE ASSEMBLY LINE: •Person 1 – Grab straw, pass to person 2 •Person 2 – Apply paperclip to one end – pass to person 3 •Person 3 – Apply paperclip to other end – pass to person 4 •Person 4 – apply straw to wave generator (start a top moving down) • *Person 1 can help apply straws since there will probably be a bottleneck with person 4
- 22. FINISHING HMWK •Finished Hmwk goes in the Blue Folder.Thursday is the absolute last day it will be accepted
- 23. Exit slip •Give the wave generator a push at the top. •How do you know that this is a transverse wave (think right angles…) •Try changing the amplitude. What do you notice about the energy required to change the amplitude?
