Question

Quizplus · Accepted Answer

The resolving power of a telescope is affected by the property of light called diffraction. Diffraction is the spreading out of light waves as they pass through an aperture or around an obstacle. The smaller the aperture, the greater the diffraction, and the lower the resolving power of the telescope.
