Question

How does the angle of deviation depend on colour or wavelength of light?

Answer 1

The angle of refraction depends on refractive index, so it also depends on the wavelength of light. The deviation of light through a prism depends on refraction, therefore it also depends on the wavelength of light. This is true whether the deviation is minimum or not.

Answer 2

hi.

The angle of refraction depends on refractive index, so it also depends on the wavelength of light. The deviationof light through a prism depends on refraction, therefore it also depends on the wavelength of light.
