Question

6) a beam of light passes from air into a medium x. It the
angle of inuderne be 72 and angle of louisson retration be you
calentate the retrailive index of malien x. (Given that sin 12 20
95l, and sin 40 = 0.642)​

Answer 1

Answer:

Given that,

Angle of incident i=72

0

Angle of refraction r=40

0

We know that,

Refractive index is

n=

sinr

sini

n=

0.642

0.951

n=1.48

Hence, the refractive index is of substance is 1.48
