1. Gravitational Waves were predicted by Albert Einstein in 1916 on the basis of his theory of Geneal Relativity
2. Gravitational waves do also exist in the Newtonian theory of Gravitation
3. Gravitational Waves are to be detected by very sensitive detectors known as Interferometers
Select the correct answer using the code given below :
Correct Answer: (b) 1 and 3 only
Solution:The result of some of the most violent and energetic processes in the Universe is gravitational waves. In 1916, these waves were identified by Albert Einstein in his general theory of relativity.However, gravitational waves were detected for the very first time in 2015. A very sensitive instrument called Laser Interferometer Gravitational-Wave Observatory (LIGO) was used by them for the detection of these waves. Therefore, the correct option is (b).
