Question

How are the angle of incidence and angle of
refraction related to each other when :
(a) a ray of light travels from rare to dense
medium,
(b) a ray of light travels from dense to rare
medium?​

Answer 1

Answer:

a) When a light Ray travels from rarer to denser medium. It shifts toward normal and angle of refraction is smaller than that of angle of incidence.

b) When light Ray travels from denser to rarer medium shifts away from normal and angle of incidence is greater than that of refraction.
