What is it about?

-----------------------------------------------------------------------------------------------------

Our project involves comparing the refraction of light in different materials using lasers.

By measuring the angle of refraction, we are able to compare the speed of light through various mediums.

The proof is Snell's law where the angle of refraction is directly proportional to the speed of light, the wider the angle of refraction, the slower light travels through the medium.

Where

*θ*is the angle between the incident light beam and the surface normal_{1}*θ*is the angle between the departing light beam and the surface normal_{2}*v*is the speed of light in the first material_{1}*v*is the speed of light in the second material_{2}*n*is the index of refraction of the first material_{1}*n*is the index of refraction of the second material_{2}

Here is an example of a laser beam bending in gelatin.
