Question

a ray of light gets refracted into air medium from crown goass of refractive index is 1.541 if angle of incidence is equal to the critical angle 40.5 then angle of refraction will be​

Answer 1

90 is angle of refraction

Answer 2

The angle of refraction is 90°

Explanation:

We know that critical angle is that value of incidence angle for which the angle of refraction is 90°

Since the angle of incidence of the ray of light is 40.5° which is given as critical angle

Therefore, the angle of refraction will be 90°

Hope this answer is helpful.
