The most modern theory of light is the quantum theory.
That theory states that light behaves as group of particles.
yes it supports the wave theory of light...
It is the wave theory of light that best explains interference. The particle theory has problems when applied to this observable phenomenon.
Light ray theory and shadows. Basically the light ray theory is the theory that light always travels in straight lines, and it is linked into shadows as when an object blocks the light rays it cannot bend round the object therefore making a shadow.
The theory of comparing light movement to dropping a pebble into a pond is called light refraction.
Give a brief account of huygen wave theory of light
Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
Christian Huygens' was one of the first to suggest that light was a wave. His theory, the wave theory of light, stated this, it was opposed by Newton's idea that light was a particle. More recently, scientists such as Thomas Young and Max Planck proved this theory with experiments. So, simply put, the wave theory states that light is a wave, which, as far as we know, is correct.
Pierre Gassendi (1592-1655), an atomist, proposed a particle theory of light.
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
mode theory assumes light to be a wave, but ray theory does not assume light to be either a wave or particle. ray theory is used to calculate properties like magnification or distance to the object or image in an optical system, where as mode theory is used find bandwidth, reflection coefficients and parallel polarization.
