Question

a light Ray travels from the air into a glass prism, making an angle of 45 degrees when with the normal to the interface on the side of the air but an angle of 28 degrees on the side with the glass. what is the index of refraction of the glass? a light Ray travels from the air into a glass prism, making an angle of 45 degrees when with the normal to the interface on the side of the air but an angle of 28 degrees on the side with the glass. what is the index of refraction of the glass? a light Ray travels from the air into a glass prism, making an angle of 45 degrees when with the normal to the interface on the side of the air but an angle of 28 degrees on the side with the glass. what is the index of refraction of the glass?

Explanation / Answer

for air refractive index n1 = 1

for glass n2 = ?

use snells law as n1 sinA = 2n2 sin B

1 * sin 45 = n2 sin 28

n2 = 1.506 is the refractive index of the glass
