Question

When blue light is replaced by yellow light, then resolving of a microscope.

• A. Increases
• B. Decreases
• C. Remains same
• D. Becomes infinite

Answer 1

The correct option is B Decreases

Resolving power of microscope $\propto \frac{1}{\lambda }$

Since, ${\lambda }_{yellow}>{\lambda }_{blue}$

Resolving power of yellow $<$ Resolving power of blue.

Hence decreases.
