Question

A light ray incident on a block of glass makes an incident angle of 50.0° with the normal to the surface. The refracted ray in the block makes an 36.1° with the normal. What is the index of refraction of the glass?

Answer 1

The index of refraction of the glass is 1.3

Step-by-step explanation:

Given data:

i = incident angle = 50°

r = refracted angle = 36.1°

The index of refraction according Snell´s law is:

`n=(1*sini)/(sinr) =(1*sin50)/(sin36.1) =1.3`
