The two forms of the law are:
<math>n_1 \sin{\theta_1} = n_2 \sin{\theta_2}</math><br/>
<math>v_1 \sin{\theta_1} = v_2 \sin{\theta_2}</math>
where:
where:
:n<sub>1</sub> and n<sub>2</sub> are the indices of [[refraction]] in media 1 and 2, respectively
:<math>n_1</math> and <math>n_2</math> are the [[Index of refraction|indices of refraction]] in media 1 and 2, respectively
:v<sub>1</sub> and v<sub>2</sub> are the velocities of light in media 1 and 2, and
:<math>v_1</math> and <math>v_2</math> are the speeds of light in media 1 and 2
:θ<sub>1</sub> and θ<sub>2</sub> are the angle from the normal of the [[plane]] dividing the 2 media and the ray.
:<math>\theta_1</math> and <math>\theta_2</math> are the angles measured from the normal and the respective ray.
The index of refraction of a material is inversely proportional to the speed of light in that material, i.e. light will move slower in a material with a high index of refraction than it will in a material with a low index of refraction.
