6. Gravitational Redshift



Gravitational redshift is a relativistic effect observed due to strong gravitational fields, which distort space-time and exert a force on light and other particles when observed from a point of lower gravitational field. In Einstein's General theory of Relativity, the gravitational redshift is a phenomenon which refers to the shift of the wavelength of a photon to longer wavelength (the red end of the spectrum) due to the gravitation field, when it is more stronger than the gravitational field at the point from which the observer observed.
