Secondary rainbows are caused by a double reflection of sunlight inside the raindrops, and are centered on the sun itself. They are about 127Â° (violet) to 130Â° (red) wide. Since this is more than 90Â°, they are seen on the same side of the sky as the primary rainbow, about 10Â° above it at apparent angles of 50â53Â°.
Have you ever seen a small rainbow on a wall in your house or school? This is formed when light is bent (refracted) through a prism (a glass object with flat, polished surfaces). The prism causes the visible light to bend, or refract. The violet light is bent more than the red and yellow light, so the colours separate. These colours-all the colours of the rainbow-make up visible light. Visible light bent (refracted) by a prism (cc) WebExhibits. Newton used a prism to split up light into the colours of the rainbow and project the rainbow onto a wall. To prove that the prism wasn't colouring visible light, he then used another prism to refract, or bend, the light back together again.
