How much more light would a 2-meter-diameter telescope gather compared with one that is 50 cm in diameter?

-48


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


How much more light can a telescope with an objective that is 31 inches in diameter gather when compared to a telescope that is 19 inches in diameter Enter the number with on units?

A nineteen inch objective gathers a bit over 4,000 times as much light as the unaided human eye. A 31 inch objective gathers about 10,670 times as much light as the human eye, or a little more than two-and-a-half times the nineteen inch objective. ======================> 2.662 times


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.


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.


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.


This telescope uses mirrors to gather and focus light energy?

Newtonian telescope


How do four telescopes of diameter 8m each gather as much light as one of diameter 16m?

Four telescopes with 8m diameter each can gather as much light as one with 16m diameter because they can be combined using interferometry techniques to effectively act as a single telescope with the equivalent light-gathering area. By correlating the signals from the individual telescopes, the resolution and sensitivity can be increased as if they were a single larger telescope.


Does the hubble space telescope use mirrors or lenses?

The Hubble Space Telescope uses mirrors to gather and focus incoming light. The primary mirror is 2.4 meters in diameter and collects light from celestial objects to produce high-resolution images. Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.


What is the name of the telescope that uses convex lenses to gather and focus light?

Refracting telescope.


A telescope that uses a set of lenses to gather and focus light from distant objects?

Refracting Telescope.
