Visible light waves are the only wavelengths of the electromagnetic spectrum that humans can see. The different wavelengths of visible light are seen as the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.

How do we see visible light?
Colours of Visible Light Spectrum
Our eyes include specialized cells known as cones. These cones act as receivers that are tuned to the wavelength of the narrowband of the EM spectrum. Light at the lower end of the visible spectrum has a longer wavelength of about 740 nm.
What are the 3 properties of visible light?
They have the wavelength in the range of 400–700 nanometers. It is responsible for the sense of sight. It is an electromagnetic radiation.
What are the 6 visible lights?
To understand how visible light is broken into various wavelengths, take a cue from Isaac Newton and shine a light through a prism. A prism separates visible white light into separate wavelengths, and each color that appears—red, orange, yellow, green, blue, and violet—is a characteristic of the distinct wavelengths.
Why do we see visible light?
The wavelengths that humans are typically able to visualize lie in a very narrow range between approximately 400 and 700 nanometers. Humans can observe and respond to stimuli created by visible light because the eyes contain specialized nerve endings that are sensitive to this range of frequencies.
