The light-gathering power of a telescope varies with the of the diameter of the lens or mirror?
Yes, that is correct. A greater main mirror, or main lens, will gather more light.

If the diameter of an objective mirror is doubled its light-gathering power becomes?
Just like any antenna used to collect electromagnetic energy at any other frequency, the 'gain' is proportional to the antenna's area. Since the area varies as the square of the collector's diameter, doubling the diameter increases the gain by a factor of 22 = 4. The corresponding increase in gain is 6 dB.
How much more light gathering power does a 5 meter diameter telescope have as compared to the human eye?
The primary mirrors of each of the two telescopes are 10 meters (33 ft) in diameter. A human eye has a pupil less than 8mm in diameter. The area of a Keck mirror is about 1,6 million times larger than that of the human pupil. (The sensors used are more sensitive too able to detect single photons).
How big does neptune look from earth?
Neptune appears as a small, bluish dot when viewed from Earth. Its angular size varies depending on its distance and position relative to Earth in its orbit around the sun. On average, Neptune's angular diameter is about 2.3 arcseconds when viewed from Earth.
10 What is the angular diameter of the sun or moon in the sky?
The angular diameter of the Sun is approximately 0.53 degrees, and the angular diameter of the Moon varies depending on its distance from Earth but ranges from about 29 to 34 arcminutes.
What is the magnitude of Pluto?
At its brightest its apparent magnitude is 13.65.
How much more light can a telescope with an objective that is 36 inches in diameter gather when compared to a telescope that is 26 inches in diameter?
About 1.92 times as much. (rounded) The so-called "light gathering power" varies in proportion to the area of the objective lens or mirror, which in turn varies as the square of its diameter. (36 inches/26 inches)2 = 1.9172 = about 2.83 dB
What is the diameter of polaris?
varies
How many meters is the diameter in a circle?

What is the diameter of meteorites?
The diameter of meteorites varies greatly, from the size of a grain of sand to the size of Mars (speculated).
What is the relationship between pump impeller diameter and pump horsepower?
The brake horsepower varies as a cube of the impeller diameter.
What is the official diameter of a cabbage ball?
8 inches exactly, it never varies. Unless in Sweden where diameter is 7.5 inches.
What is the diameter of a dodgeball?
The size varies but average is about 1-1.5 feet
What is the cost of a car mirror?
The cost of a car mirror varies depending on the type of mirror: mechanical or electric. Car mirrors may range in prices from sixty to one hundred dollars.
Why can't you give just one number to describe the earth's diameter?
The Earth is not a perfect sphere. The diameter varies depending on where you measure it.
The image formed by a convex spherical mirror will always be what?
The nature of the image is not constant. It varies with the distance between the object and the mirror.
