Question

refraction of prism and dispersion of white light​

Answer 1

The deviation of light from its original course due to it changing the optical material it was travelling through is called refraction. A deeper understanding of this requires the proper understanding of Huygen’s Principle.

For now we will see that the light incident on a prism will follow Snell’s Law, sin(i)sin(r)=μ2μ1 where i is angle of the incident ray and r is the angle of the emergent ray.
