What is also called the spectrum of white light?

The spectrum of white light is often referred to as the visible spectrum, which encompasses all the colors that can be seen by the human eye. When white light passes through a prism, it separates into its constituent colors—red, orange, yellow, green, blue, indigo, and violet—forming a continuous spectrum. This phenomenon illustrates how white light is made up of various wavelengths, each corresponding to a different color.
