Gravitational redshift is a phenomenon in physics resulting from the gravitational field’s influence on the frequency (and wavelength) of electromagnetic waves, such as light. According to Einstein’s general theory of relativity, gravity affects the passage of time and the frequency of light in a gravitational field. In regions of stronger gravitational pull, like near massive objects, time dilates, and light experiences a shift towards the red end of the electromagnetic spectrum. This gravitational redshift has practical applications, aiding scientists in measuring gravitational fields, studying celestial bodies, and verifying predictions of general relativity. It plays a crucial role in understanding the interplay between gravity and electromagnetic radiation in the universe.
