Aray of light traveling in air is incident on the flat surface of a piece of glass at an angle of 65.9° with respect to the normal to the surface of the glass. if the ray refracted into the glass makes an angle of 34.8° with respect to the normal, what is the refractive index of the glass?

= 1.6

Explanation:

= Angle of incidence = 65.9°

= Angle of refraction = 34.8°

= Index of refraction of air = 1

= Index of refraction of glass = ?

Using Snell's law

Sin =

(1) Sin65.9 =   Sin34.8

= 1.6
