Question

The resolving power of a microscope can

be increased by

(A) Increasing diameter of objective lens

(B) Increasing diameter of eye lens

(C) Increasing wavelength of light used

(D) decreasing wavelength of light used​

Answer 1

Answer:

A) Increasing diameter of objective lens

Explanation:

One way of increasing the resolving power of microscope is to use immersion liquids between the front lens of the objective and cover lens. So, here the increasing diameter of the objective lens will only increase the resolving power of the microscope.

Answer 2

Answer:

ans is option D) by decreasing wavelength of light used

Explanation:

# as formula of resolving power

R.p = n sin theta / lambda

# thus R.p is inversely proportional to wavelength of light (lambda)
