Explain how EM waves are able to be seen

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength ... When all the waves are seen together, they make white light. Visible light is a form of electromagnetic (EM) radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Generally, visible light is defined as the wavelengths that are visible to most human eyes. This broad range of wavelengths is known as the electromagnetic spectrum
