Question

derive the law of refraction of light using Huygens principle​

Answer 1

Answer:

Snell's law of refraction using Huygen's Principle : Consider a plane wavefront AB incident on a surface PQ separating two media 1 and 2. ... The angle is also equal to the angle between the incident plane wavefront BA and the surface of separation PQ. So ∠BAD is the angle of incidence of the incident plane wavefront AB.
