Is it true that It is more difficult to produce large mirrors for telescopes that have large objective lenses?
It is generally more challenging to produce large mirrors for telescopes compared to large lenses because mirrors need to be ground and polished to a very high precision to avoid distortions and aberrations in the images produced. Lenses can also suffer from similar issues, but the methods to correct them are different and often less complex. Additionally, mirrors are usually easier to support and maintain their shape compared to large lenses.
How do telescope Works?
Mirrors and lenses in telescopes bend and focus light to produce an image with more detail.
What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
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.
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.

What is the use of concave and convex mirror?
Concave mirrors are used to focus light, to produce a parallel beam in car headlights, and so you can have a close look while shaving. Convex mirrors are used for making telescopes, viewfinders in vehicles, and used in supermarkets or stores as surveillance as it gives a wider view.

A refracting telescope produce an image using an?
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.
Where we use concave mirror?
Concave mirrors are used in makeup mirrors, headlights of cars, reflecting telescopes, and solar concentrators. They can focus light to produce real or virtual images depending on the object's position relative to the mirror.
What are the advantage of concave mirror?
Concave mirrors can reflect light to a single focal point, making them useful for focusing light, creating magnified images, and in devices like telescopes and shaving mirrors. They can also produce virtual images that appear larger than the object itself.
Can convex mirrors produce real images?
No, convex mirrors cannot produce real images. They only produce virtual images.
Which type of mirror produces the most accurate reflection?
Concave mirrors produce the most accurate reflection because they converge light rays towards a focal point, creating a clear and magnified image. This type of mirror is often used in telescopes and shaving mirrors for precision reflection.
Does the hubble space telescope use mirrors or lenses?

Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.
What are the advantages and disadvantages of concave mirrors?
Advantages of concave mirrors include their ability to focus light to produce real, inverted images and their use in devices like telescopes and headlights. Disadvantages include image distortion at the edges, as well as the difficulty of obtaining a clear, focused image when the object is too close to the mirror.
Five difference between a concave mirrors and convex mirrors?
Concave Vs Convex 1. Mercury coating will be made on the convex side but here on concave side. So reflecting portion would become concave and here convex 2. Both real and virtual images but only virtual images 3. Both diminished, enlarged and even same size images formed but only diminished. 4. Both inverted (real) and erect (virtual) images but only erect images. 5. Used as shaving mirror and in telescopes but used as rear view mirror
