What does an electromagnetic wave consist of?
and electric and magnetic wave that travel together and vibrate.
3 of 9
How are electromagnetics wave seen?
At right angles to each other and to the direction they are travelling in, they are also in phase with each other. reaching a peak together they are in step.
4 of 9
How are photons emitted?
They are emitted by a charged particle when it loses energy.
5 of 9
what are the conditions to meet when a photon is emitted?
- A fast moving electron is stopped slows down or changes direction.
- An electron in a shell moves to a different shell of lower energy.
6 of 9
what is the equation to find out a photons energy?
E = Plancks constant x frequency
7 of 9
what is a laser beam?
it is consistent of photons of the same frequency, its power is being transferred per second by photons.
8 of 9
How do yo find the power of the beam?
power of the beam = number of photons passing each second x Planck's constant x frequency
