This particle is the namesake a sphere whose radius is three-halves times the Schwarzschild radius.
This particle is the namesake a sphere whose radius is three-halves times the Schwarzschild radius. The effect of gravity on these particles was indicated by the Pound-Rebka experiment. The frequency of these particles is changed in Raman Scattering, and their momentum changes in Compton scattering. The interaction of these particles with a strong electric field can result in the production of an electron and positron in pair production. These particles are created in stimulated emission. For 10 points, name these particles of electromagnetic radiation that make up light.
