FTP, name this effect which won for its discoverer the 1961 Nobel Prize in physics.
The first laboratory test of Einstein's general theory of relativity, and it confirmed the prediction that the wavelength of electromagnetic radiation, including gamma rays, increases as the gravitational field increases. Named for a Cal Tech professor, this effect holds that certain radioactive atoms, when present in a crystalline structure, emit or absorb gamma rays in an extremely narrow range of wavelengths.
