Which of the following is NOT a challenge faced by observatories?

  1. Light pollution

  2. Atmospheric turbulence

  3. Cloud cover

  4. Lack of funding

Show answer
Correct Option: D
Explanation:

Lack of funding is not a challenge faced by observatories, as they are typically funded by governments or private institutions.

What is the term for the blurring of images caused by atmospheric turbulence?

  1. Seeing

  2. Scintillation

  3. Chromatic aberration

  4. Astigmatism

Show answer
Correct Option: A
Explanation:

Seeing is the term for the blurring of images caused by atmospheric turbulence.

Which type of telescope is most affected by light pollution?

  1. Refracting telescope

  2. Reflecting telescope

  3. Catadioptric telescope

  4. Radio telescope

Show answer
Correct Option: A
Explanation:

Refracting telescopes are most affected by light pollution because they collect light from a wider area of the sky than reflecting telescopes.

What is the main limitation of radio telescopes?

  1. They can only observe objects that emit radio waves.

  2. They have poor resolution.

  3. They are very expensive to build.

  4. They are difficult to operate.

Show answer
Correct Option: A
Explanation:

The main limitation of radio telescopes is that they can only observe objects that emit radio waves.

Which of the following is NOT a way to reduce the effects of light pollution on observatories?

  1. Using filters to block out unwanted light

  2. Moving the observatory to a darker location

  3. Educating the public about light pollution

  4. Building a dome around the observatory

Show answer
Correct Option: D
Explanation:

Building a dome around the observatory will not reduce the effects of light pollution.

What is the term for the phenomenon in which stars appear to twinkle?

  1. Scintillation

  2. Seeing

  3. Chromatic aberration

  4. Astigmatism

Show answer
Correct Option: A
Explanation:

Scintillation is the term for the phenomenon in which stars appear to twinkle.

Which of the following is NOT a type of adaptive optics used to correct for atmospheric turbulence?

  1. Multi-conjugate adaptive optics

  2. Laser guide star adaptive optics

  3. Shack-Hartmann wavefront sensor

  4. Lucky imaging

Show answer
Correct Option: D
Explanation:

Lucky imaging is not a type of adaptive optics used to correct for atmospheric turbulence.

What is the main challenge faced by observatories located at high altitudes?

  1. Thin air

  2. Extreme weather conditions

  3. Lack of oxygen

  4. All of the above

Show answer
Correct Option: D
Explanation:

Observatories located at high altitudes face a number of challenges, including thin air, extreme weather conditions, and lack of oxygen.

Which of the following is NOT a limitation of infrared telescopes?

  1. They can only observe objects that emit infrared radiation.

  2. They are affected by atmospheric absorption.

  3. They are very expensive to build.

  4. They have poor resolution.

Show answer
Correct Option: D
Explanation:

Infrared telescopes do not have poor resolution.

What is the main challenge faced by observatories located in urban areas?

  1. Light pollution

  2. Radio interference

  3. Seismic vibrations

  4. All of the above

Show answer
Correct Option: D
Explanation:

Observatories located in urban areas face a number of challenges, including light pollution, radio interference, and seismic vibrations.

Which of the following is NOT a type of telescope that can be used to observe X-rays?

  1. X-ray telescope

  2. Chandra X-ray Observatory

  3. Hubble Space Telescope

  4. XMM-Newton

Show answer
Correct Option: C
Explanation:

The Hubble Space Telescope cannot be used to observe X-rays.

What is the main limitation of ultraviolet telescopes?

  1. They can only observe objects that emit ultraviolet radiation.

  2. They are affected by atmospheric absorption.

  3. They are very expensive to build.

  4. They have poor resolution.

Show answer
Correct Option: B
Explanation:

Ultraviolet telescopes are affected by atmospheric absorption.

Which of the following is NOT a challenge faced by observatories located in remote areas?

  1. Lack of access to infrastructure

  2. Extreme weather conditions

  3. High cost of transportation

  4. All of the above

Show answer
Correct Option: C
Explanation:

High cost of transportation is not a challenge faced by observatories located in remote areas.

What is the main challenge faced by observatories located near bodies of water?

  1. Humidity

  2. Fog

  3. Salt spray

  4. All of the above

Show answer
Correct Option: D
Explanation:

Observatories located near bodies of water face a number of challenges, including humidity, fog, and salt spray.

Which of the following is NOT a type of telescope that can be used to observe gamma rays?
