Question

which colour deviate minimum during the dispersion of light through a prism?

Answer 1

red deviate minimum during dispersion

Answer 2

Wavelength is inversely proportional to the deviation in the path of the light. Red light suffers the least amount of deviation and violet the most. When a white light is made to pass through a prism, formation of a spectrum of seven colors occurs showing white light is a combination of seven separate colors.
