Question

You are shopping for telescopes online. You find two in your price range. One of these has an aperture of 20 cm, and the other has an aperture of 30 cm. If aperture size is the only difference, which should you choose, and why?

Answer 1

Answer:

30 CM one because the light gathering power will be better

Explanation:

Based on the information provided within the question it can be said that in this scenario the best option that you can choose from would be the 30 CM one because the light gathering power will be better on that one as opposed to the 20cm one. In telescopes the larger the lens, the clearer the image will be  as it allows more light to enter and cause the image to be sharper.
