Q:

# How does a prism work?

A:

A prism works by slowing down light proportionally to wavelength as it enters into the prism, which causes the rainbow effect. Light changes speed as it moves from the air to another substance. This causes the light to change course.

In order to achieve the effect, the light must enter the prism at an angle. The light then bends once it is inside the prism and again when the light leaves the prism. Each wavelength of light gets bent at different angles. This causes each color to fan out and become more distinct.

A prism has a polygonal base and a face opposite and congruent to the base, while a pyramid has a polygonal base and an apex at the opposite side. The edge of the pyramid's base and its apex form a triangle, and the number of sides of its base dictate how many triangular faces are present in the pyramid.
