Question

the refractive index of water and glass are 1.33 and 1.5 respectively if angle of incidence in water is 60° then find the angle of refraction in glass​

Answer 1

ANSWER

48.59 degree

CONCEPT USED

snells law

n1sini = n2 sinr

CALCULATION

1.33× sin60 = 1.5 sinr

sinr = 1.33× √3 / 2 × 1.5

r = sin^(-1) (0.75)

r = 48.59 degree
