When light passes into a telescope, it undergoes diffraction. As a result, the image becomes slightly blurred. The extent of diffraction depends on the diameter of the opening through which the light enters the telescope and on the wavelength of the light. Which combination of diameter and wavelength would give the clearest image (with the least blurring)?
- Adiameter large, wavelength long
- Bdiameter large, wavelength short
- Cdiameter small, wavelength long
- Ddiameter small, wavelength short
