Expert Solution
Concept and Principle:
  • When a photon is leaving a gravitational source it will lose energy in the gravitational field. This will shift the frequency of the photon to smaller frequencies.

 

  • The wavelength of such photons will be shifted to a longer wavelength. Such photons are called redshifted.

 

  • The change in wavelength due to gravity is given by,

Δλλ=GMRc2

Here G is the universal gravitational constant, M is the mass of the gravitational source, R is the radius of the gravitational source, and c is the speed of light.
