Nature of Light and Principle Dr. Amar Chandra Das Ghosh

The nature of waves. ... A linear wave is a disturbance which travels through a medium such as air or water. Fluids such as these can be thought of as consisting of a large number of “particles”, each of which consists of a vast number of molecules. Wave nature of Light: Light is a transverse, electromagnetic wave that can be seen by humans. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.

Who discovered the wave nature of light? Wave Nature of Matter: de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle. The Davisson-Germer experiment demonstrated the wave-nature of matter and completed the theory of wave-particle duality. Experiments demonstrated that de Broglie hypothesis is applicable to atoms and macromolecules. Who discovered the wave nature of light? The mathematical theory of electromagnetism by James Clerk Maxwell, set up in 1864, led to the view that light is of electromagnetic nature, propagating as a wave from the source to the receiver. Heinrich Hertz discovered experimentally the existence of electromagnetic waves at radio-frequencies in the 1880s.Dec 2, 1999

What is difference between wave and particle? What is wave nature? In 1924, Louis de Broglie suggested that just as light exhibits wave and particle properties, all microscopic material particles such as electrons, protons, atoms, molecules etc. have also dual character. They behave as a particle as well. What is difference between wave and particle? Originally Answered: What is the difference between a particle and a wave? Aparticle is a localized point in the space. More than one particle cannot be present at a given position in space. Particles do not show the phenomenon of interference

A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. Its most basic form as a function of time (t) is: Y (t) = A Sin ( 2𝝅𝒇𝒕+ φ ) = A Sin ( ωt + φ ) where: A = the amplitude, the peak deviation of the function from zero. f = the ordinary frequency, the number of oscillations (cycles) that occur each second of time. ω = 2πf, the angular frequency, the rate of change of the function argument in units of radians per second φ  = the phase, specifies (in radians) where in its cycle the oscillation is at t = 0. When   is non-zero, the entire waveform appears to be shifted in time by the amount  /ω seconds. A negative value represents a delay, and a positive value represents an advance.
