Question

The resolving power of a microscope depends upon:

• A. The focal length and aperture of the eye lens.
• B. The focal length and objective of the eye lens.
• C. The apertures of the objective and the eye lens.
• D. The wavelength of light illuminating the object.

Answer 1

The correct option is D

The wavelength of light illuminating the object.

Resolving power: It is the inverse of the distance between two objects that can be just resolved.

The diagram to represent the resolving power:

Resolving power of microscope: It depends upon the wavelength of the light illuminating the object.

The formula to calculate the resolving power of the microscope:

$R.Pofmicroscope=\frac{2\mu \sin \theta }{\lambda }$

The correct option is D.
