	Brewster's angle refers to the angle at which the glare off of the gel's surface is most polarized, thus allowing for a maximum amount of light to be removed by the polarizer.		Brewster's angle refers to the angle at which the glare off of the gel's surface is most polarized, thus allowing for a maximum amount of light to be removed by the polarizer.

	Equation: <math>\ tan{/theta} = \frac{n2}{n1} </math>		Equation: <math>\ tan(theta) = \frac{n2}{n1} </math>

	~~When n1 is considered to be the index of refraction of air, the tangent of Brewster's angle is approximately equal to the index of refraction of the gel, n2.~~

			When n1 is considered to be the index of refraction of air, the tangent of Brewster's angle is approximately equal to the index of refraction of the gel, n2.

	Many of Brewster's discoveries are still in use today including his contributions to the lighthouse. Brewster's angle is also used when determining the reflection of light in certain materials. Understanding this reflection of light is important in many engineering applications.		Many of Brewster's discoveries are still in use today including his contributions to the lighthouse.
