Answer 2

Dear Student,

◆ Answer -

r = 36.23°

● Explaination -

# Given -

i = 52°

n = 4/3

r = ?

# Solution -

According to Snell's law -

n = sini / sinr

Rearranging,

sinr = sini / n

sinr = sin52° / (4/3)

sinr = 0.7882 / 1.333

sinr = 0.5912

Taking sin inverse,

r = arcsin(0.5912)

r = 36.23°

Therefore, angle of refraction is 36.23°.

Thanks buddy for asking. Hope this helps you...
