What is the index of refraction of a refractive medium if the angle of incidence in air is 30 and the angle of refraction. Is 15

Index of refraction is 2.

Explanation:

Step 1: Given details are angle of incidence (i) = 30 and angle of refraction (r) = 15 Step 2: Refractive Index can be calculated by the formula n = sin i/sin r

⇒ n = sin 30/sin 15

⇒ n = 0.5/0.25 = 2
