The double slit experiment shows that electrons can behave as both particles and waves. When shot through a single slit, electrons form a single band like particles. However, when shot through two slits, electrons form an interference pattern of multiple bands like waves. This wave-particle duality means that elementary particles exhibit both wave and particle properties. The experiment demonstrates that electrons behave as particles through one slit but as waves through two slits.

Electricity is atomic
Electricity is produced through the movement of electrons between atoms. Normally, electrons orbit the nucleus of an atom but can be removed by adding energy. Some atoms have outer electrons that are farther from the nucleus and more easily removed. Copper and silver are good electrical conductors because their outer electrons are farther from the nucleus and repelled by multiple electron layers, making them easier to remove with just a small amount of energy. While silver is a slightly better conductor, copper is more commonly used due to its lower cost and greater abundance.
PT IRE
The document discusses periodic trends in atomic properties including atomic radius, ionization energy, and electronegativity. It explains that as you move down a group in the periodic table, atomic radius increases while ionization energy and electronegativity decrease due to increased electron shielding. However, as you move across a period, atomic radius decreases while ionization energy and electronegativity increase due to the stronger effective nuclear charge pulling electrons in more tightly.

The document discusses the atomic structure and properties of metals, insulators, and semiconductors. Metals conduct electricity well due to their free electrons, are shiny as electrons scatter light, and are stiff yet ductile from electron bonding. Insulators like ceramics and polymers do not conduct as their electrons are locked in ionic or covalent bonds, making them stiff or brittle. Semiconductors have properties between metals and insulators with fewer free electrons. Their conductivity increases with temperature unlike metals but can also be controlled through doping with other atoms to donate or accept free electrons.
Chemical effects o electric current
Electrons flow through wires, which provide a path for electric current. When electric current flows through a wire connected to a light bulb, the filament is heated to a high temperature, causing it to glow. Conductors allow the flow of electric current, while insulators do not allow electric current to pass through.
Static electricity and electrical currants
Static electricity is the buildup of positive or negative charges on the surface of objects, caused by electrons moving between objects during physical contact like rubbing. It differs from current electricity which involves the controlled flow of electrons through conductors. Conductors allow electron flow while insulators do not. Static charges are created by the imbalance and redistribution of electrons on and between objects, and can cause static shocks when excess electrons jump between two charged objects and their charges equalize.
what is Diode
Nikhil Raut from RCOEM Nagpur is presenting about diodes. A diode is a two-terminal semiconductor component that allows current to flow in only one direction. It works by taking advantage of the properties of intrinsic and extrinsic semiconductors like silicon and germanium, which are materials that have electrical conductivity between that of conductors and insulators. When a P-type and N-type semiconductor are joined, it forms a PN junction that only allows current to flow from P to N under forward bias, and blocks it under reverse bias. Different types of diodes include Zener diodes, tunnel diodes, LEDs, and Schottky diodes.

The Double Slit Experiment by Danilo Veljovic
The Double slit experiment. In this slideshow, behaviours of matter, elementary particles, and waves are compared as they are fired through slits.
Double slit interference and wave particle duality
Double slit interference experiments can show wave-like behavior for both waves and particles. Young's double slit experiment with light showed an interference pattern, demonstrating that light acts as a wave even though it was thought to be a particle based on earlier experiments. Later, Einstein introduced the idea that light behaves as both a particle (photon) and wave, based on observations from the photoelectric effect. This helped establish the principle of wave-particle duality in quantum mechanics.
Ph 101-8
The document discusses the wave properties of particles. Some key points:
1) Louis de Broglie hypothesized in 1924 that matter has an associated wave-like nature with a wavelength given by Planck's constant divided by momentum.
2) A particle can be represented as a localized "wave packet" resulting from the interference and superposition of multiple waves with slightly different wavelengths and frequencies.
3) Davisson and Germer's electron diffraction experiment in 1927 provided direct evidence of the wave nature of electrons and supported de Broglie's hypothesis by measuring electron wavelengths matching those expected.

The photoelectric effect provides evidence that light behaves as particles. When light shines on a metal surface, electrons can be emitted. This is explained by assuming that light is made up of particles called photons, with each photon having an energy determined by its frequency. The kinetic energy of the emitted electrons depends on the frequency of the incident light, not its intensity. This is consistent with a particle model where each photon transfers its energy to an electron. The wave-particle duality of light is evidenced by both its particle-like properties in the photoelectric effect and its wave-like properties demonstrated in phenomena such as interference and diffraction.
Finalphysics
This document discusses the wave-particle duality of light. It describes early theories that light was either a wave (wave theory) or particle (particle theory). Later, Max Planck proposed that light has both wave-like and particle-like properties, exhibiting wave-like interference and diffraction patterns but also behaving as discrete packets of energy (photons) when interacting with matter. Albert Einstein further developed this idea by hypothesizing that the photoelectric effect was caused by photons of light energizing electrons. The double slit experiment also demonstrates light's dual nature by showing it can form interference patterns like a wave even when passing through the slits one photon at a time.

The document provides an overview of the history of radiation and basic concepts related to radiation. It discusses how radiation was discovered in the late 19th century by scientists like Roentgen, Becquerel, and Curies. It then describes the atomic models developed by Thomson, Rutherford and Bohr to explain the structure of atoms and different types of radiation. Finally, it discusses different types of radiation, dose quantities measured by dosimeters, and commonly used personal dosimeters like TLD badges and film badges.
Light
This document discusses the nature of light and summarizes the key theories about what light is. It describes light exhibiting properties of both waves and particles. The wave theory proposed by Huygens stated that light is a wave, which was supported by experiments on reflection, refraction, interference and diffraction. The particle theory was proposed by Newton, but Young's experiment on interference demonstrated light's wave properties. Maxwell's electromagnetic theory described light as electromagnetic waves that can travel through a vacuum. The quantum theory reconciled both wave and particle descriptions, explaining that light behaves as both waves and particles.

Photon Concept of Light (Grade 12 ).pptx
The double-slit experiment provided evidence that electrons behave like waves by producing an interference pattern. The photoelectric effect experiment showed that light consists of discrete packets of energy called photons which eject electrons from metal surfaces. The Compton scattering experiment found that X-ray photons lose energy when scattering off electrons, supporting the photon model of electromagnetic radiation and its particle-like properties. Together these experiments helped establish the dual wave-particle nature of both light and matter.
