Question

how can we get white colors by mixing

Answer 1

Dear student,
If we mix red green and blue light we get white light. These 3 colours are primary colour.
White colour can also found be mixing of all 7 colour of rainbow spectrum.The colour that are seen are the result of wavelengths of light reflected to the eyes. Normally, eyes cannot distinguish these wavelengths and can only see all colours mixed in a wave of white light.
