# What is the equation for Snell's law?

where

Then you need to isolate your unknown.

Example:

Light in air (

(Isolate sin

(1.0003) (sin 35.0) / 1.52 = sin

0.5737 / 1.52 = sin

0.3775 = sin

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
