Answer:
Explanation:
The reason why the focal length of a lens depends on the wavelength is the same as the reason why a glass prism can separate the wavelength of light into a rainbow: the refractive index (μ in your question, I presume) depends on the wavelength of the light. This is called dispersion.

No never. Wavelength of light doesn't change the focal length of the lense.
please explain it
