MCQ
The resolving power of a compound microscope will be maximum when
  • A
    Red light is used to illuminate the object
  • ✓
    Violet light is used to illuminate the object instead of red light
  • C
    Infra red light is used to illuminate the object instead of visible light
  • D
    The microscope is in normal adjustment
✓

Answer

Correct option: B.
Violet light is used to illuminate the object instead of red light
b
(b)

Resolving power $\propto \frac{1}{\lambda}, \lambda_{\text {red }} > \lambda_{\text {violet }}$
