The light gathering power is directly proportional to the light gathering area, so all you have to do is figure out the ratio of the areas of the two scopes. Another answer: Do you remember fourth grade arithmetic? Do you remember pi r square?
Yes, light gathering power is proportional to the area of the objective. The more light a telescope can gather, the better the telescope will be able to allow the user to see.
A reflecting telescope.
The Hubble Space Telescope can see out to a distance of several billions of light-years.

Gathering and focusing light from distant objects.
a. a small diameter reflecting telescope.
radio telescope detects radio waves and a light telescope views light waves.

70 mm. The numbers refer to the diameter of the main lens or mirror; the larger this number, the more light-gathering the telescope is, and also, the higher its resolution will be.70 mm.

No, you can change the magnification of the telescope by simply changing the eyepiece. The two most important powers of the telescope, light-gathering power and resolving power, depend on the diameter of the telescope, but it does not control the magnification.
9 times greater.
It will become 9 times as great.
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.
Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.
