- Wavelength (λ) is directly proportional to wave speed (v) when frequency (f) is constant (λ = v/f). - Electromagnetic waves travel much faster than mechanical waves (like ultrasonic waves) in the same medium.
When the frequency of an electromagnetic wave and ultrasonic wave are same, then

- Which of the following statements is /are correct ? 1. Gravitational Waves were predicted by Albert Einstein in 1916 on the basis of his theory of General 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 :
- Albert Einstein predicted the existence of gravitational waves in 1916 as a consequence of his theory of General Relativity. This statement is correct. 2. The Newtonian theory of Gravitation describes gravity as an instantaneous force between masses. It does not predict the existence of gravitational waves which are ripples in spacetime propagating at the speed of light. This statement is incorrect. 3. Gravitational waves are extremely weak and require highly sensitive detectors. Interferometers, such as those used in the LIGO (Laser Interferometer Gravitational- Wave Observatory) and Virgo experiments, are the primary instruments used for their detection.
