The resolution of a microscope can be most improved by
A) increasing the wavelength and the diameter of the lens.
B) decreasing the wavelength and the diameter of the lens.
C) decreasing the wavelength and increasing the diameter of the lens.
D) increasing the wavelength and decreasing the diameter of the lens.

Question

Quizplus · Accepted Answer

Decreasing the wavelength of light increases the resolving power of a microscope. Using a lens with a larger diameter also improves the resolution, as it allows more light to enter the lens and provides a larger area for the light to spread out. Therefore, the best choice is to decrease the wavelength and increase the diameter of the lens, which is option C. Increasing the wavelength and decreasing the diameter of the lens (option D) would actually decrease the resolving power.
