Question

does focal length of a lens depend on the colour of the light used

Answer 1

Explanation:

Focal length is the property of lens and colour of light is dependent of wavelength. So focal length of the lens is independent of the colour, wave length and frequency of the light which is passing through the lens. Note: Refraction of light is colour dependent.

Answer 2

Answer:

HI THERE

Explanation:

Remember focal length is the property of lens and colour of light is dependent of wavelength. So focal length of the lens is independent of the colour, wave length and frequency of the light which is passing through the lens.
