Question

Resolving power of a microscope is a function of ____________

• A. Wavelength of light used
• B. Numerical aperture of lens system
• C. Refractive index
• D. Wavelength of light used and numerical aperture of lens system

Answer 1

Answer:

D. Wavelength of light used and numerical aperture of lens system

The ability of a microscope to distinguish two adjacent points as distinct and separate is known as resolving power. Resolving power is a function of wavelength of light used and the numerical aperture (NA) of the lens system. NA refers to the refractive index of the medium multiplied with the sine value of the half-aperture angle.
