Question

What is resolution of a telescope? What physical process limits it?

a) Resolution is the ability to see distant objects clearly. It is limited by atmospheric turbulence.
b) Resolution is the ability to magnify objects. It is limited by the telescope's size.
c) Resolution is the ability to distinguish fine details. It is limited by the telescope's weight.
d) Resolution is the ability to detect color in objects. It is limited by the observer's eyesight.

Answer 1

Resolution refers to the precision of detail present in an image, limited by atmospheric turbulence and diffraction in telescopes.

Step-by-step explanation:

Resolution refers to the precision of detail present in an image, specifically the smallest features that can be distinguished. It is not related to magnification or the ability to detect color.

Resolution in telescopes is limited by atmospheric turbulence and also by diffraction, which is the spreading and blurring of light as it passes through the telescope's lens or mirror. Diffraction limits the resolution of any system having a lens or mirror, including telescopes.

Therefore, the correct answer is option a) Resolution is the ability to see distant objects clearly. It is limited by atmospheric turbulence.
