Question

question 11
which power of a telescope is the least important?
magnifying power
light - gathering power
all the powers are equally important
resolving power

Explanation:

The light - gathering power determines how bright the image is, and the resolving power determines the ability to distinguish fine details. Magnifying power just enlarges the image but doesn't add new information if the light - gathering and resolving powers are insufficient. So magnifying power is the least important.

Answer:

magnifying power
