Question

Q. Consider the following statements with reference to the Gravitational waves:

Which of the above statements is/are incorrect?

• A. 1 and 2 only
• B. 2 only
• C. 1 and 3 only
• D. 3 only

Answer 1

The correct option is C 1 and 3 only

Explanation:

Statement 1 is incorrect:

• Detection of Gravitational waves will support Einstein’s General Theory of Relativity.
• Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.
• While formulating his General Theory of Relativity, Einstein proposed that gravitational attraction was a result of the bending of the fabric of space-time by the equivalent of a heavy object

Statement 2 is correct

• The detection of gravitational waves would enable astrophysicists and astronomers to “see” the universe which is, as of now, invisible to them. Almost 95 percent of the universe is known to consist of dark matter and dark energy, which does not emit any light or any other electromagnetic waves, and therefore, has not been detected even by the most sophisticated instruments.
• Black holes, for example, cannot be “seen” but they do produce gravitational waves, and now can be detected using these

Statement 3 is incorrect:

• The LIGO India project will come up in Maharashtra, near Aundha in the Hingoli district.
