If the angle of incidence in air is 30 degrees, and it enters glass making an angle of refraction of 22 degrees, what is the refractive index of glass?

1.36

1.52

1.75

1.00

Answer and Solution

B. 1.52

Using Snell's Law: n = sin(30)/sin(22), we find the refractive index to be approximately 1.52.
