Can someone tell me; when an electron changes orbits and throws off its energy in the form of a photon; this travels at the speed of light which is around 186,000 miles per second, right ?
What I am wondering is does the photon as soon as it leaves the atom accelerate upto this speed (even if the acceleration is immensly quick) OR does it just "jump" from 0 speed to the speed of light without any acceleration at all ?
