Question

Explain Newton's Corpuscular Theory, Huygen's Wave theory, Maxwell's Electromagnetic Theory and Max-Plank's Quantum Theory..

Answer 1

Newton’s corpuscular theory of light is based on the following points
1. Light consists of very tiny particles known as “corpuscular”.
2. These corpuscles on emission from the source of light travel in straight line with high velocity
3. When these particles enter the eyes, they produce image of the object or sensation of vision.
4. Corpuscles of different colours have different sizes.

Huygen’s wave theory of light

 In 1679, Christian Huygens proposed the wave theory of light.
According to huygen’s wave theory:
1. Each point in a source of light sends out waves in all directions in hypothetical medium called "ETHER".
2. Light is a form of energy 
3. Light travels in the form of waves.
4. A medium is necessary for the propagation of waves & the whole space is filled with an imaginary medium called Ether
5. Light waves have very short wave length
