How is the size of a reflecting telescope indicated?
The size of a reflecting telescope is typically indicated by its aperture, which is the diameter of the primary mirror. Aperture size plays a crucial role in determining the light-gathering ability and resolving power of the telescope.
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.
What kind of telescope do you need to look into space?
You would need a telescope with a large aperture to observe objects in space clearly. Aperture size is important for collecting enough light from distant objects. A telescope with a minimum aperture of 4 inches is recommended for observing celestial objects such as galaxies, nebulae, and star clusters.
What does the light gathering ability of a telescope depend on?
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.
What power of an optical telescope is most affected by light pollution?
A small aperture.
What part of a reflecting telescope would you measure to find the apeture?
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.

What makes a telescope powerful?
The light-gathering power of a telescope is determined by its aperture, which refers to the width of a telescopes primary mirror or objective lens.

What is the root and the root meaning of aperture?
The act of opening., An opening; an open space; a gap, cleft, or chasm; a passage perforated; a hole; as, an aperture in a wall., The diameter of the exposed part of the object glass of a telescope or other optical instrument; as, a telescope of four-inch aperture.
What is the Lens aperture of the hubble telescope?
The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).

A telescope with a minimum aperture of 4 inches is recommended for observing celestial objects such as galaxies, nebulae, and star clusters.
Is aperture of a spherical mirror equals to its diameter?
No, the aperture of a spherical mirror is not necessarily equal to its diameter. The aperture refers to the effective opening through which light can enter and be reflected by the mirror, which can be smaller than the overall diameter of the mirror. In many cases, the aperture is defined by the area of the mirror that is used for focusing light, while the diameter is simply the total width across the mirror.
What would be the focal ratio of a telescope with a 5 aperture and a focal length of 25?
The focal ratio ( 'f' number ) is the ratio of focal length to diameter. For the numbers given in the question, assuming they're both in the same unit, this telescope is a 25/5 = f/5.
What does the light gathering ability of a telescope depend on?
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.
What is the diameter of the chandra telescope?
It is 33 METERS in diameter
What is the aperture of a spherical lens?
The word aperture does not apply to the lens itself. In a camera, the aperture is the diameter of the shutter opening which allows light to reach the lens.
