What is the effect of increasing the aperture of a telescope on its diffraction-limited resolution?.
- A.Resolution improves with larger aperture
- B.Resolution decreases with larger aperture
- C.Resolution remains unchanged with larger aperture
- D.Resolution is not affected by aperture size
Model answer
What a good answer should say
- Resolution improves with larger aperture
Explanation
Why this works
A larger aperture allows more light to enter the telescope, which reduces the effects of diffraction and improves the resolution. This means finer details can be observed in astronomical images.
