Hi All! I'm Armenia,learning in the faculty of Physics in our State University. Recently while one of lectures we talked about time,what is it. The lecturer said that it's something that is moving on without stopping but I disagreed and said that no time exists, time is just a way of arranging...

Hi Everyone! I'm new here and like this forum. Can anyone tell me how the electron moving roundly in atom doesn't emit EM waves while changing it's speed?

Yes I know the process but read attentively please. I just said that not only UV light emits, but 632,8nm EM wave too which is in the red portion of the visible spectrum.

But as I know lasers emits not only UV light Sir!?

it's because of the object you Chose! How lasers work?they are getting energy from the light (electrons get to higher states) and when you turn off the light electrons get to lower states by turn-emitting EM waves in the frequencies we see,but there are lot's of objects that emits EM waves in...

and not only electron-all the electric charges receives or emits EM(photons) energy while changing it's speed.

Hi! As I know electron while changing it's states always receives or emits only EM energy (photons)!
