Question

For convex lens focal length will be maximum for which colour

Answer 1

Dear Student,

◆ Answer -

For convex lens focal length will be maximum for Red color.

● Explanation -

Focal length of convex lens is directly proportional to wavelength of light passed. As red light has higher wavelength, it refracts less and has greater focal lens. On the contrary, blue light converges more and has small focal length.

Thanks dear. Hope this helps you..

Answer 2

The colour with maximum focal length  as asked in the question would be red colour.

Explanation:

• When all the colours pass through a glass lens like in a Prism that into bend more or less as per their wavelengths.
• The colour violet and the colour blue having the smallest wavelengths tend to bend more and since when more they are more likely to make a focal length much closer to the lens.
• But in case of red colour the bending of the colour, due to its speed and wavelength, happen less.
• Since the bending is less in case of red colour the focal length will be more.
