Which of the following statements is / are correct?
- 1Gravitational Waves were predicted by Albert Einstein in 1916 on the basis of his theory of General Relativity.
- 2Gravitational waves do also exist in the Newtonian theory of Gravitation.
- 3Gravitational Waves are to be detected by very sensitive detectors known as Interferometers.
Select the correct answer using the code given below:
general-sciencephysics-mechanics
- A1 only
- B1 and 3 only
- C2 and 3 only
- D1, 2 and 3
Explanation
Statements 1 and 3 are correct: Einstein predicted gravitational waves in 1916 from general relativity, and they are detected by highly sensitive laser interferometers (LIGO/Virgo). Statement 2 is wrong: gravitational waves do not exist in Newtonian gravitation, which assumes instantaneous action at a distance. Hence 1 and 3 only.
