Question

If a ray of light does not undergo refraction at a surface dividing two media, then the

angle of incidence is​

Answer 1

Answer:

angle of incidence is perpendicular to both the medias

hope it will be helpful for you!!!

Plz plz mark as brainliest!!

Answer 2

Answer:

Both reflection and refraction occur due to interaction of light with the atoms at the surface of separation. ... As the light emitted by these charged oscillators is equal to their own frequency of oscillation, so both the reflected and refracted lights have the same frequency as the frequency of incident light.
