Question

what is gravitational red shift??❤️❤️❤️​

Answer 1

Answer:

In Einstein's general theory of relativity, the gravitational redshift is the phenomenon that clocks deeper in a gravitational well tick slower when observed from outside the well. ... In the latter case the 'clock' is the frequency of the photon and a lower frequency is the same as a longer ("redder") wavelength.

Answer 2

Explanation:

In Einstein's general theory of relativity, the gravitational redshift is the phenomenon that clocks deeper in a gravitational well tick slower when observed from outside the well. ... In the latter case the 'clock' is the frequency of the photon and a lower frequency is the same as a longer wavelength.
