When the object is self-luminous, the resolving power of a microscope is given by the expression

Options

A. inversely proportional to numerical aperture
B. directly proportional to wavelength
C. directly proportional to numerical aperture
D. independent of numerical aperture.

Answer

C

Explanation

Resolving power of a microscope `=(2musinbeta)/(1.22lambda)`
Where `mu sin beta` is called numerical aperture of the microscope and `lambda` is the wavelength of light used.
