What is the primary method of observation used in modern Indian astronomy?

  1. Optical telescopes

  2. Radio telescopes

  3. X-ray telescopes

  4. Infrared telescopes

Show answer
Correct Option: A
Explanation:

Optical telescopes are the most widely used type of telescope in modern Indian astronomy. They collect visible light from celestial objects and focus it to form an image.

Which of the following is not a type of optical telescope?

  1. Refracting telescope

  2. Reflecting telescope

  3. Catadioptric telescope

  4. Schmidt telescope

Show answer
Correct Option: D
Explanation:

The Schmidt telescope is a type of catadioptric telescope, which means that it uses both lenses and mirrors to focus light. It is not a type of optical telescope.

What is the largest optical telescope in India?

What is the primary method of data collection used in modern Indian astronomy?

  1. CCD cameras

  2. Photographic plates

  3. Spectrometers

  4. Radiometers

Show answer
Correct Option: A
Explanation:

CCD cameras are the primary method of data collection used in modern Indian astronomy. They are electronic devices that convert light into an electrical signal.

Which of the following is not a type of CCD camera?

  1. Frame transfer CCD camera

  2. Interline transfer CCD camera

  3. Full-frame CCD camera

  4. Active pixel sensor CCD camera

Show answer
Correct Option: D
Explanation:

Active pixel sensor CCD cameras are not a type of CCD camera.

What is the largest CCD camera in India?

  1. The Giant Metrewave Radio Telescope (GMRT)

  2. The Aryabhatta Research Institute of Observational Sciences (ARIES)

  3. The Vainu Bappu Observatory (VBO)

  4. The Kavalur Observatory

Show answer
Correct Option:
Explanation:

There is no single largest CCD camera in India. The size of a CCD camera depends on the specific telescope it is used with.
