- n. Plural form of photon.
Examples
“They discovered that light comes in discrete packets, or quanta, which we call photons”
“Traveling at almost the speed of light (and therefore "relativistic"), these feather weight electrons collide with photons from the cosmic microwave background.”
“Electromagnetic radiation is emitted in discrete units known as photons that travel at the speed of light as electromagnetic waves.”
“The photons from the sun are necessary for life on earth.”

“Just as the energy in waves of light is carried in quantized particle-like units called photons, so, too, is plasmonic energy carried in quasi-particles called plasmons.”
“Just as the energy in waves of light is carried through space in discrete or quantized particle-like units called photons, so, too, is the energy in waves of charged gas (plasma) carried in quantized particle-like packets called plasmons, as they travel along metallic surfaces.”
“a delay of a few microseconds with respect to the photons from the annihilation event.”

“The collection proceeds through Einstein's 1905 proof that "particles of light"—later dubbed photons—were real, to the application of these ideas to atomic physics and the revelation in the 1920s that the quantum world is stranger than anything that had been imagined.”
“Particles of light, called photons, leave a source ... and pass through two slits in a screen interfere with each other ... and form bands of light and dark on screen.”
“Below the other mirror the interference is constructive since the wave phase of the photons is the same and the photon waves reinforce each other.”
