Question

The resolving power of compound microscope will increase with

• A. Decrease in wavelength of light and increase in numerical aperture.
• B. Increase in wavelength of light and decrease in numerical aperture.
• C. Increase in both wavelength of light and numerical aperture.
• D. Decrease in both wavelength of light and numerical aperture.

Answer 1

The correct option is A Decrease in wavelength of light and increase in numerical aperture.

• The resolving power of a compound microscope can be defined as the ability of the microscope to form separate images of two objects placed very close to each other.
• The resolving power of the compound microscope will increase with a decrease in wavelength of light and an increase in the numerical aperture.
  
• So, the correct answer is 'Decrease in wavelength of light and an increase in the numerical aperture'.
