Light spectrum

The light spectrum is the range of colors that can be seen when white light is separated into its component parts using a prism. The colors of the spectrum can be thought of as a rainbow, with red at one end and violet at the other. It is made up of an array of colors including red, orange, yellow, green, blue, indigo, and violet. An analogy for understanding the light spectrum is to imagine a garden hose. If you turn on a garden hose, water flows out in a continuous stream. The light spectrum is like the water in the garden hose – just as the garden hose can be broken down into individual droplets, white light can be broken down into its component colors. Fun fact: the light spectrum is also referred to as the visible spectrum because it is the only part of the electromagnetic spectrum that humans are able to see.
