Question 1:

Which type of astronomy primarily deals with the study of visible light from celestial objects?

Explanation: Optical Astronomy primarily deals with the study of visible light from celestial objects. This is the most common form of astronomy, and most telescopes on Earth operate in the optical range.

Question 2:

Which of the following statements is true about adaptive optics in optical astronomy?

Explanation: Adaptive optics in optical astronomy involves adjusting telescope mirrors in real-time to correct for atmospheric distortions, resulting in sharper and clearer images of celestial objects.

Question 3:

What is the main advantage of radio astronomy compared to optical astronomy?

Explanation: The main advantage of radio astronomy compared to optical astronomy is that radio waves can penetrate through interstellar dust, allowing astronomers to study objects and phenomena that are not easily observable in the optical range.

Question 4:

What is the purpose of interferometry in radio astronomy?

Explanation: Interferometry in radio astronomy involves combining signals from multiple radio telescopes to create a virtual telescope with the resolution of a much larger single telescope. This technique allows for higher resolution observations and the ability to image fine details of celestial objects.

Question 5:

Which phenomenon in radio astronomy is associated with rapidly rotating neutron stars?

Explanation: Rapidly rotating neutron stars, known as pulsars, emit beams of radio waves that are detectable on Earth. These pulsating signals are a distinct phenomenon in radio astronomy.
