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

Options

  1. Adecreases
  2. Bincreases
  3. Cremains same
  4. Dfirst increases and then decreases

Correct answer

A. decreases

Step-by-step solution

Magnifying power of a simple microscope =1+ D f Focal length of red light is greater than the focal length of blue light. Hence, the magnifying power will decrease.
