Why are most large telescope reflecting telescopes?
It is cheaper and easier to create mirrors rather than lenses. Large lenses become difficult to support the larger they become. Additionally, mirrored telescopes fold light waves so that a telescope can be shorter, the same size telescopes with lenses are greater in length.
What property of an optical telescope is associated with sharper images?
The sharpness of images in an optical telescope is often associated with its resolving power, which is determined by the size of the telescope's objective lens or mirror. A larger objective size allows the telescope to collect more light and resolve finer details in the observed objects.
How do you improve the resolution?
Get a bigger telescope. Resolution is proportional to the size of the telescope. But due to the atmosphere, there is a practical limit beyond which it makes no difference what the telescope size is.
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.
How reflecting telescope compare to refracting telescope?
Reflecting telescopes use mirrors to collect and focus light, which allows for larger apertures and eliminates chromatic aberration, a common issue in refracting telescopes that use lenses. Refracting telescopes rely on glass lenses to bend light, but they can suffer from distortions and are typically limited in size due to the weight and cost of large lenses. Overall, reflecting telescopes are generally preferred for professional astronomy due to their versatility and ability to produce clearer images at larger scales.

The type of telescope uses convex lenses to increase the size of the image viewed?
According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting

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 limits the size of a refracting a telescope and why?
Mass. A refracting telescope needs to be either really long, or have really thick lenses. In either case, the mass of the telescope limits how large you can make it, if you want to be able to change its direction.
What is the good thing about relfecting telescope?
It gathers more light than a refractor type of telescope can, of the same size.
What is a western astronomical telescope worth?
The size of a telescope depends on many factors, but mainly, on its size. For example, a telescope with a diameter (of the main lens or mirror) of 100 mm will cost much less than one with a diameter of 500 mm.
What makes the Hubble telescope from the other telescope?
the hubble telescope is a refracting telescope and it is the biggest one because the refracting telescope can only have a certain range of size for the glass lens because it can only hang on the telescope and it is aproximently 5 meters big the lens. hope it helped
