• Visible light has a wavelength in the range of 400-700 nanometers (nm).

• The portion of visible light lies between infrared and ultraviolet in the electromagnetic spectrum.

• The infrared spectrum has longer wavelengths.

• The ultraviolet spectrum has shorter wavelengths.

• Red color has a maximum range in the spectrum of visible light.

• The red color has the longest wavelength (700nm).

• Violet color has the shortest wavelength (400nm).
