Huygens‘ Principle, Laws of Reflection and Refraction on the Basis of Wave Theory

Each point on a wave front acts as a new source of the disturbance. The disturbances from these points are secondary wave lets. These wavelets spread out in all directions in the medium with the velocity of light. This note provides us an information on Huygens‘ principle, laws of reflection and refraction on the basis of wave theory. Learn More

Measurement of Velocity of Light

The first measurement of the velocity of light was made by Fizeau in 1849. This note provides us an information on measurement of velocity of light. Learn More
