To determine
The correct statement about the telescopes having different aperture size.
Expert Solution & Answer
![Check Mark](/static/check-mark.png)
Answer to Problem 1QP
Option (c)
Explanation of Solution
Light gathering power of a telescope is proportional to the square of aperture.
Here,
Conclusion:
The equation shows that higher the aperture size, higher will be the light gathering power. Thus, option (c) is correct.
20 cm telescope will have less gathering power. Thus, option (a) is incorrect.
Image size is not related to aperture size. Thus, option (b) and (d) are incorrect.
