Newton's Corpuscular Theory:
Newton's corpuscular theory of light states that
1. Light is emitted form of tiny particles is known as corpuscles.
2. The corpuscles travel with the velocity of light.
3. When corpuscles strike the surface they caused to sensation of light.
4.Medium is essential for propagation of light.
5. Velocity is greater in denser medium as compared to rare medium.
6. The velocity of light depends upon the temperature of the body emitting the light.
