Question

Why are there limits to the resolving power of a telescope?(A) The aperture is a double slit.(B) The aperture is a slit with two edges.(C) The aperture through which the light passes limits the amount of light thatforms the image.(D) The aperture through which the light passes diffracts the light and blurs theimage.

Answer 1

Answer:

the aperture through which the light passes diffracts the light and blurs the image.

Option D is correct

Step-by-step explanation:

The limits of resolution in a telescope is described by the Rayleigh criterion.

As light passes through the small regular aperture in the telescope, the light bends around obstacle in its path (i.e. it diffracts). The aperture produces a blurry or fuzzy image instead of a bright one.

Therefore, we can conclude that the limits to the resolving power of a telescope is because the aperture through which the light passes diffracts the light and blurs the image.
