In the case of a photon, for which m=0, the equation boils down to E=pc. Because photons move at the speed of light regardless of where we view them from, they have momentum, and therefore energy.

That looks strangely similar to the equation for the energy of a photon. Yup. If you like, you can use light with a frequency of f to induce the transition from one energy level to another.

Very soon after the Big Bang, the universe enjoyed a brief phase where quarks and gluons roamed freely, not yet joined up ...

Photon–photon collision is theorized to be a fundamental means by which matter is generated in the universe, and it arises from Einstein's well-known equation ... and whose energy is a million ...

The team confirmed that it only takes one photon to set the reaction in motion ... Just putting a plant outside in the Sun causes it to generate the energy it needs to survive, grow, and reproduce.

Using a groundbreaking new technique, researchers have unveiled the first detailed image of a photon — a single ... down and solve an infinite number of equations to reach an answer," Yuen ...

For photosynthesis, one photon is all it takes. Only a single particle of light is required to spark the first steps of the biological process that converts light into chemical energy, scientists ...

Photons appear and disappear randomly within the cavity due to tiny energy fluctuations in space that cause quantum particles to blink in and out of existence. However, once there, the photon is ...
