## 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

n

_{1}sinσ

_{1}= n

_{2}sinσ

_{2}

## The Attempt at a Solution

σ

_{1}= 60°

σ

_{2}= 30°

sinσ

_{1}/ sinσ

_{2}= n

So, is this right?
