Optical Instruments & the Eye

Simple microscope is used to see the object first in blue light and then a red light. Due to the change from blue to red light, its magnifying power

Show answer and solution

Answer: (a)

Magnifying power of a simple microscope: $M = 1 + \dfrac{D}{f}$ .
$\mu_{red} < \mu_{blue} \Rightarrow f_{red} > f_{blue}$ , so $M$ becomes smaller.
So the answer is (a) decreases.
