If the focal length of a double convex lens for red light is

{f_R}

, its focal length for the violet light is

View answer and explanation

Correct option: C

Less than

{f_R}

Option C (Less than

{f_R}

) is correct because the refractive index for violet light is higher than for red light, leading to a shorter focal length.
