How does focal length of a lens depends on the wavelength of light passed through?according to me the focal length should not change as focal length is a physical quantity of a lens so it should not change.

yes focal length does not change s with change in wavelength

Answer:
The focal length of the lens varies directly with the wavelength of the light used and as wavelength is inversely related to refractive index, the focal length also varies inversely with it. This is the principal cause of the phenomena of chromatic aberration. The frequency of light has no effect on the focal length.
