<u>Answer:</u>
Gravitational redshift, changes in a planet’s orbital path, gravitational lensing provides the concrete evidence for the general theory of relativity.
<u>Explanation:</u>
- Due to the slowing of time in very 'strong gravitational field' the gravitational redshift occurs.
- The low frequency of the light occurs in the red part when we observe the electromagnetic spectrum.
- The appearance of light is seen slightly shifted to the 'red wavelength'.
- The matter in the galaxies that bends the light from a source at a distance reaching the observer is also a evidence which is termed as gravitational lensing.
