How much more light does a 1 m telescope gather than a 10 cm telescope How many magnitudes fainter should be detectable by a 1 m telescope than by a 10 cm telescope?
Notsurewhattoput
The light-gathering power of an objective lens or mirror is proportional to its area, or equivalently,
to the square of its linear dimensions (radius, diameter, circumference).
If the focal ratios ('f' number) are the same, then the 1-m scope scoops up 102 = 100 times as much light
as the 10-cm job.
100 times difference in brightness is exactly the mathematical definition of six (6) magnitudes brighter/dimmer.

This telescope uses mirrors to gather and focus light energy?
Newtonian telescope
What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
Does a reflecting telescope gather light with a lens or a mirror?
reflecting telescope gathers light from mirror
Does a reflecting telescope gather light with a lens?
No, with mirrors; but there are lenses in the ocular that do gather the light from the mirror and make an image you can see with your eyes.
What is meant by the size of a telescope?
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.
Which type of telescope uses a mirror to gather light?
A reflecting telescope.
What telescope doesn't use mirrors or lenses to gather light?
A radio telescope.
