Question:
The maximum focal length of convex lens is for:
The maximum focal length of convex lens is for:
Show Hint
Light with longer wavelengths, like red light, tends to have the largest focal length in a convex lens, due to its lesser refraction compared to shorter wavelengths.
Updated On: Mar 3, 2025
- Blue light
- Green light
- Red light
- Yellow light
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The focal length of a lens is dependent on the wavelength of the light passing through it. For a convex lens, the focal length is greatest for red light, as it has the longest wavelength.
