Step-by-step explanation:

Normally if you ask someone the colors of visible light you will get the answer: VIBGYOR (An acronym for Violet, Indigo, Blue, Green, Yellow, orange and Red). All the colors differ in their wavelength. Red has the longest wavelength and Violet has smallest wavelength. The wavelengths of different colors are given below:

Red: 620 to 750 nm

Orange: 590 to 620 nm

Yellow: 570 to 590 nm

Green: 495 to 570 nm

Blue: 450 to 495 nm

Indigo: 425 to 450 nm

Violet: 380 to 425 nm
