Answer 2

Dear Student,

◆ Answer -

c = 45°

● Explanation -

Given that refractive index of the material is √2. i.e. n = √2.

Critical angle for the pair of media is related to refractive index by formula -

sinc = 1/n

sinc = 1/√2

Taking sin inverse,

c = arcsin(1/√2)

c = 45°

Hence, critical angle for the material is 45°.

Tnanks dear. Hope this helps you...
