Homework Statement



A light beam incident on a glass slide at an angle of 60 ˚, being partly reflected and partly refracted. It notes that reflected and refracted beams are each at 90 ˚ What is the refractive index of glass?

Homework Equations



n1sinσ1 = n2sinσ2

The Attempt at a Solution



σ1 = 60°
σ2 = 30°

sinσ1 / sinσ2 = n

So, is this right?
