Angle =48.59°

Explanation:

To find: Find angle of refraction in a medium (M=2) . If light is incident in vacuum making angle equal to twice the critical angle .

Given: M=2

Solution :

MsinФc =1

Фc= 30°

Light is incident in vacuum making angle equal to twice the critical angle.

Фt=60°

M1sinФt= M2sinФc

⇒1×√3/2=2×sinФ

⇒sinФ=√3/4

⇒Ф= sin-1(3/4)

⇒Ф=48.59°
