The light collecting power of a telescope depends on the diameter of its objective lens or primary mirror. A larger objective lens or mirror can gather more light, allowing the telescope to produce brighter and clearer images of celestial objects.

Does the diameter of a telescope control its magnification?
No, the diameter of a telescope's objective lens or mirror determines its light-gathering ability and resolving power, while the magnification is determined by the ratio of the focal length of the objective lens or mirror to the eyepiece.
How much greater is the light-collecting area of one of the 10-meter Keck telescopes than that of the 5-meter Hale telescope?
The light-collecting area of a telescope is proportional to the square of its diameter, so the light-collecting area of a 10-meter Keck telescope is 4 times greater than that of a 5-meter Hale telescope.
What are the 4 properties of a telescope?
The four main properties of a telescope are its aperture (diameter of the primary lens or mirror), magnification (how much larger the telescope makes distant objects appear), focal length (distance from the lens or mirror to the focal point), and resolution (the ability to distinguish fine details or separate closely spaced objects).
What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
What power of an optical telescope is most affected by light pollution?
A small aperture.
Why does the light gathering power of a telescope vary?
The light gathering power of a telescope is directly proportional to the area of the objective lens of the telescope.

No, the diameter of a telescope's objective lens or mirror determines its light-gathering ability and resolving power, while the magnification is determined by the ratio of the focal length of the objective lens or mirror to the eyepiece.

How can you determine the light gathering power ratio between a 1 meter telescope and a 10 meter telescope?
The light gathering power of a telescope is proportional to the square of its diameter. Therefore, the light gathering power ratio between a 1 meter telescope and a 10 meter telescope would be (10/1)^2 = 100. This means that the 10 meter telescope would gather 100 times more light than the 1 meter telescope.
The light gathering power of a telescope increases as the objective increases?
Yes, the light gathering power of a telescope is directly proportional to the surface area of its objective lens or mirror. A larger objective can collect more light, allowing for brighter and clearer images to be observed. This increased light gathering power is beneficial for viewing faint or distant objects in space.

What power of an optical telescope is most affected by light pollution?
A small aperture.
What is the ratio of the light gathering power of a 1.39 m telescope to that of a 0.79 m telescope?
(1.39/0.79)2 = about 3.1 (rounded)
How many times bigger does the image appear in a refracting telescope?
The image in a refracting telescope appears bigger by the magnification factor provided by the telescope's eyepiece. This is typically around 50-100 times for most amateur telescopes.
A telescope that suffers from chromatic aberration and has a low light gathering power is most likely?
a cheap refracting telescope with a simple lens system. Chromatic aberration occurs when different colors of light focus at different points, and low light-gathering power could be due to a smaller aperture size.
How far out can a hubble telescope see?
The Hubble telescope with the light-collecting power of the W. M. Keck Telescopes can see 13 billion light years away based on the furthest detected galaxy to date. In comparison looking up into the sky on a very clear night, the Triangulum Galaxy can sometimes be seen by the naked eye. This is a distance of 3.14 million light years. The Andromeda Galaxy is also sometimes visible. This is a distance of 2.5 million light years.
