from where the light photons get energy to move at such a high speed?do they keep on moving forever?

Question

from where the light photons get energy to move at such a high speed?do they keep on moving forever?

In: Physics

Answer 1

Electromagnetic waves travel at the speed of light. But sometimes electromagnetic waves also behave like particles (Called particle-wave duality) and are modeled as such. The name, they gave these particles, was photon.

Since the photons are electromagnetic waves, they will travel at the speed of light.
