Question

If the refraction index of glass is 1.5, Angle of incidence is 30°then find the angle of refraction

Answer 1

Answer:

Explanation:

Given,

The angle of incidence = 30

Refractive index = 1.5

We know that the sin of the angle of incidence to the sin of the angle of refraction is called the refractive index

Substitute the known values, we obtain

➡1.5 = Sin30/Sin of the angle of refraction

➡1.5 = 1/(2 × Sin of the angle of refraction)

➡Sin of angle of refraction = 1/(2 × 1.5)

➡Sin of angle of refraction = 10/30

➡Sin of angle of refraction = 1/3

So,

➡Angle of refraction = Sin^(-1)1/3

Hence, the angle of reflection is sin inverse 1/3
