The diameter of the objective lens of the microscope makes an angle β at the focus of the microscope. Further, the medium between the object and the lens is the oil of the refractive index n . Then the resolving power of the microscope.

Options

  1. AIncreases with decreasing value of β
  2. BIncreases with increasing value of n sin 2 β
  3. CIncreases with increasing value of 1 n sin 2 β
  4. DIncreases with decreasing value of n

Correct answer

B. Increases with increasing value of n sin 2 β

Step-by-step solution

R . P . microscope = 2 n sin 2 β λ ⇒ R . P . ∝ n sin 2 β
