A ray of light traveling in air is incident on the flat surface of a piece of glass at an angle of 64.0° with respect to the normal to the surface of the glass. If the ray refracted into the glass makes an angle of 34.3° with respect to the normal, what is the refractive index of the glass?

Answer #1

using the snell's law we have

n1 sin a1 = n2 sin a2

n1 = refractive index of air

n2 = refractive index of glass

1 sin 64 = n2 sin 34.3

n2 = 1.594

refractive index of glass = 1.594
