Question

what colours make up white light​

Answer 1

Answer:

White light is made up of the following colours: red, orange, yellow, green, blue, indigo, and violet. Each coloured light has its own wavelength. Red light has the longest wavelength and violet light has the shortest wavelength.

Answer 2

Answer:

Each colour has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light.
