Definitions for "Gravitational redshift"
The shift in wavelengths toward the red end of the spectrum, caused by a gravitational field
the shift in wavelength of electromagnetic radiation (light) created by a body's gravitational field as the radiation moves away from the body. Only extremely dense objects, such as white dwarfs, produce a significant redshift of their radiation.
The redshift of electromagnetic radiation caused by a gravitational field. The slowing of clocks in a gravitational field.
