हिन्दीThe ratio of resolving powers of an optical microscope for two wavelengths \( \lambda_1 = 4000\text{ \AA} \) and \( \lambda_2 = 6000\text{ \AA} \) is
View Answer & Solution
Correct answer · Option B
\( 3:2 \)
Explanation
Resolving power of microscope \( RP = \frac{2n\sin\theta}{\lambda} \), so \( RP \propto \frac{1}{\lambda} \). Thus \( \frac{RP_1}{RP_2} = \frac{\lambda_2}{\lambda_1} = \frac{6000}{4000} = \frac{3}{2} \).
