Will the focal length of a lens for red light be more, same or less than that for blue light ?

Will the focal length of a lens for red light be more, sam or less than that for blue light

Is the focal length of a lens the same for lights of all colors ?

If the focal length of a double convex lens for red light is f_(R) its focal length for the violet light is

Red light is incident on a think converging lens of focal length f. Briefly explain how the focal length of the lens will change,if red light is replaced with blue light.

If the focal length of a lens for red and violet light rays respectively are f_R and f_V then which of the following is true relationship ?

Assertion : The focal length of the lens does not change when red light is replaced by blue light. Reason : The focal length of lens does not depends on colour of light used.

How does focal length of a lens change when red light is replaced by violet light?

A: When white light passes through lens then refraction of violet light is more than that of red light. R: For given lens, focal length of red light is more than that of violet light.
