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.

A 1 m telescope gathers 100 times more light than a 10 cm telescope since the area of the aperture is proportional to the square of the diameter. This means that a 1 m telescope can detect objects that are 5 magnitudes fainter than a 10 cm telescope since each magnitude corresponds to a factor of 2.5 in brightness.

Why does the diameter of the telescope aperture matter?
The diameter of the telescope aperture determines how much light the telescope can gather, which impacts the brightness and detail of the images it can produce. A larger aperture means more light can be collected, allowing for clearer and sharper views of celestial objects.
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.
Why does a larger telescope allow astronomers to see more?
A larger telescope has a greater light-collecting area, which allows it to gather more light from faint objects in space. This increased light-gathering ability improves the telescope's sensitivity and ability to detect fainter objects, providing astronomers with clearer and more detailed images. Additionally, a larger telescope can have higher resolution, allowing for sharper and more detailed observations of celestial objects.
What is meant by the size of a telescope?
The size of a telescope refers to its aperture, which is the diameter of the main mirror or lens. A larger aperture allows the telescope to gather more light, which can result in brighter and clearer images.
