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.
Know MoreIn 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.

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.
Full Answer >A pentagonal prism has five lateral faces and two pentagonal bases, which equal seven faces. A prism has two congruent polygons that form the top and bottom of the shape. These polygons are referred to as bases. The remaining sides are referred to as lateral faces.
Full Answer >The volume of a prism is worked out by first calculating the area of the surface and then multiplying that figure by the length of the prism. This applies whatever the shape a prism takes.
Full Answer >A pentagonal prism has 10 vertices because there are two five-sided shapes at both ends of a prism. A pentagonal prism has 15 edges and seven faces. Five faces are between the pentagons on each end.
