Question

Q3.For the same angle of incidence in media P,Q,R, the angles of
refraction are 45, 35 and 15, in which medium will the velocity of light be
minimum with diagram​

Answer 1

Answer:

where n aair =1

∴ 1×sini=n×sinr ⟹n= sini/sinr

Velocity of light in a medium v= c/n= c*sinr/sini ⟹v ∝sin r

Thus velocity of light is minimum in medium A.
