Gravitational radiation is an effort, in a lecture format, to describe the aspects of gravitational radiation, often as applied in the performance of astrophysics.

You are free to take this quiz based on the lecture gravitational radiation astronomy at any time.

To improve your score, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: Have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information from more familiar points of view, or be creative with association.

Enjoy learning by doing!

Quiz[edit]







  

1

Yes or No, Gravitational radiation is radiation produced from particles traveling along curved paths near the speed of light.

Yes
No

2

True or False, 3C 48 was the first source in the Third Cambridge Catalogue of Radio Sources for which an optical identification was found through interferometry.

TRUE
FALSE

3

Evidence that demonstrates that a model or idea versus a control group is feasible with respect to gravitational radiation is called a

.

4

Yes or No, Because in most accelerators the particle trajectories are bent by magnetic fields, gravitational radiation is also called Magneto-Bremsstrahlung.

No
Yes

5

True or False, FRI objects typically have bright jets in the centre, while FRIIs have faint jets but bright hotspots at the ends of the lobes.

TRUE
FALSE

6

Complete the text:

A short or

realization of a certain

or idea to

a treament's feasibility regarding gravitational radiation is called a proof of

7

Yes or No, Gravitational radiation can be very highly polarized (50%) if the field is globally ordered.

Yes
No

8

True or False, The signal induced by a potential gravitational wave is thus "embedded" in the light intensity variations detected at the interferometer output.

TRUE
FALSE

9
