Which type of telescope uses a concave mirror as its primary objective?

  1. Refracting Telescope

  2. Reflecting Telescope

  3. Catadioptric Telescope

  4. Radio Telescope


Correct Option: B
Explanation:

Reflecting telescopes use a concave mirror as the primary objective to gather and focus light.

What is the primary function of a telescope?

  1. To magnify distant objects

  2. To collect more light

  3. To enhance the resolution of images

  4. All of the above


Correct Option: D
Explanation:

Telescopes perform all of these functions: magnifying distant objects, collecting more light, and enhancing the resolution of images.

Which type of telescope uses a combination of lenses and mirrors?

  1. Refracting Telescope

  2. Reflecting Telescope

  3. Catadioptric Telescope

  4. Radio Telescope


Correct Option: C
Explanation:

Catadioptric telescopes use a combination of lenses and mirrors to achieve high-quality images.

  2. Keck I and Keck II Telescopes

  3. Very Large Telescope (VLT)

  4. Subaru Telescope


Correct Option: A
Explanation:

The Gran Telescopio Canarias (GTC) is the largest optical telescope in the world, with a primary mirror diameter of 10.4 meters.

Which type of telescope is used to study radio waves emitted by celestial objects?

  1. Refracting Telescope

  2. Reflecting Telescope

  3. Catadioptric Telescope

  4. Radio Telescope


Correct Option: D
Explanation:
