This document describes Newton's rings experiment to determine the wavelength of sodium light. When a spherical glass surface is placed on a flat surface, interference patterns of concentric bright and dark rings are formed due to the varying thickness of the air gap between the surfaces. By measuring the diameter of different rings and using the known radius of curvature, the wavelength can be calculated using an interference equation. The experiment involves using a monochromatic light source to illuminate the surfaces and observing the ring patterns under a microscope to measure ring diameters and calculate the wavelength.
1. Diffraction refers to the bending of light around obstacles or through openings, and results in interference patterns.
2. There are two main types of diffraction: Fresnel diffraction occurs when light passes near an obstacle, while Fraunhofer diffraction occurs when light passes through or around objects and the observation is made far from the obstacle.
3. Diffraction gratings consist of many parallel slits and cause light to diffract into several beams. The angles and intensities of these beams can be determined through analysis of interference from the multiple slits.
Relativistic formulation of Maxwell equations.dhrubanka
This document discusses the relativistic formulation of Maxwell's equations. It begins by introducing the key concepts of special relativity that are needed, including Lorentz transformations and four-vectors. It then shows how the electric and magnetic fields transform under Lorentz transformations and how they can be combined into the electromagnetic field tensor. The document also discusses how charge and current densities transform and satisfy the continuity equation as a four-vector. Finally, it presents Maxwell's equations in their compact relativistic form in terms of the field tensor and its derivatives.
The document discusses infrared therapy (IRT), including its sources, classification, physiological effects, therapeutic effects, dangers, technique of application, dosage, and contraindications. IRT uses infrared radiation to provide superficial heating that increases local temperature, metabolism, blood flow, and other physiological effects. Common applications of IRT include relief of pain and muscle relaxation by accelerating healing. Precautions must be taken to avoid burns and other dangers when applying IRT.
Hijama (cupping) therapy an overview by Dr MOHD SHAHID (MD) MOHD SHAHID
The document provides a historical overview of cupping therapy (hijama), describing it as an ancient practice mentioned as far back as 3300 BC. It discusses the types of cupping (dry and wet), principles to follow when performing it, its modes of action in drawing out impurities and toxins, and research studies supporting its efficacy for conditions like diabetes, dysmenorrhoea, and sciatica. The conclusion emphasizes that modern science has proven the benefits of cupping therapy for many diseases and that it activates the body's natural healing abilities through detoxification.
The document discusses interference of light using Michelson's interferometer. It begins with an introduction to light as an electromagnetic wave and the principles of superposition and interference. It then describes Young's double slit experiment and details the construction, working principle and applications of Michelson's interferometer, including determining the wavelength of light and wavelength separation of nearby wavelengths. Examples of problems using the interferometer are given along with solutions. The document provides a comprehensive overview of interference and Michelson's interferometer.

5. Uniwersytet Mozarteum :
• Pierwotnie znany jako Przykatedralne Towarzystwo
Muzyki Sakralnej i Mozarteum. Towarzystwo
założone zostało 22 kwietnia 1841w Salzburgu.
6. Mozartkugel- pralinki:
• Czekoladki w kształcie kuli, stworzone przez
cukiernika Paula Fürsta w Salzburgu w 1890 roku i
nazwane na cześć Wolfganga Amadeusza Mozarta .
10. Na chrzcie nadano mu imiona
Joannes Chrysostomus Wolfgangus
Theophilus,
pierwsze na cześć świętego
katolickiego patrona, Wolfgang na
pamiątkę dziadka ze strony matki,
a Teofil na pamiątkę ojca chrzestnego
11. Przez większość życia kompozytor
posługiwał się jednak
imionami Wolfgang Amadé.
Amadé to francuska
wersja greckiego imienia Teofil
(przyjaciel Boga lub umiłowany przez
Boga).
12. Wcześniej używał także wersji włoskiej
(Amadeo). We wczesnych dokumentach
występowała również forma Wolfgang
Gottlieb (Gottlieb to niemieckie tłumaczenie
dla Teofil). Natomiast nigdy nie używał
najpowszechniejszej dzisiaj
wersji łacińskiej Amadeus. W dzieciństwie
rodzice używali również
zdrobnień Wolferl, Wolfgangerl i we
wczesnych czasach Wolfi, o czym wiadomo z
listów ojca i innych źródeł.
13. Falco - Rock Me Amadeus
• piosenka z niemieckim tekstem, a z refrenem

ponowa przez braci Bolland i Falco.
• Rock me Amadeus pozostaje do dziś jedynym
niemieckojęzycznym numerem jeden w USA.
• "Rock Me Amadeus" tekstowo nawiązuje do

muzycznie jest mieszaniną rocka, rapu i
muzyki dyskotekowej.
14. „Amadeusz”
