Pink Floyd and Physics

The album cover of Pink Floyd's album, The Dark Side of the Moon, is pictured below. This physics phenomenon occurs because of the differences in speeds of different color light through a medium. The colors have different frequencies which cause discrepancies in their indices of refraction. Violet, having the highest frequency, is refracted the most and moves slowest through the medium. Red, on the other hand, has the lowest frequency and moves quickest through the medium. The differences in speed cause differences in locations of the light as they exit the prism created a fantastic array of the rainbow. Thank you physics for giving Pink Floyd such an awesome album cover.
