Question

Light ray is travelling from one optical medium 2 other. Both the media have same refractive indeces. Ifangle of incidence is 60°, then angle of refraction will be​

Answer 1

Answer:

Given, μ=21w.r.t. air i=45∘,r=?

Also, μ=sinrsini

⇒21=sinrsin45∘⇒21=sinr1/2

⇒sinr=1

⇒r=90∘

Note that the ray is incident from denser medium and is refracted into a rarer medium air.

Answer 2

Answer:

Good morning have a great day
