Sample Question 1
What is the scientific definition of "aperture" in a telescope?

The length of the telescope tube

The diameter of the main lens or mirror

The weight of the telescope base

The magnification power of the eyepiece

The color of the telescope frame

Sample Question 2
A telescope with a larger aperture acts like a larger "bucket" for catching starlight.

True

False

Sample Question 3
In reflecting telescopes explained to students, what part determines the aperture size?
