Hi there.
00:01
So for this problem, we are told that a photon produces an electron and a positron.
00:07
So we have a photon that decays then in an electron and a positron.
00:23
With that said, the question, and we are told that each has a kinetic energy of 220 kilo -electron, 220 kilo electron balls.
00:42
So the question is to find the energy and the wavelength of the phantom.
00:47
Now with that said, we know that there should be conservation of energy.
00:54
So the initial energy should be equal to the final energy.
00:58
Now the final energy is the sum of these two energies.
01:05
So that will be two times 220 kilo -electron balls.
01:11
So that will be 440 kilo -electron balls.
01:15
So this should be the final energy.
01:17
Then this energy should be equal to the energy, the initial energy for the photon.
01:26
So the energy of the photon should be equal to 440 kilo -electron balls.
01:33
So that's the solution for.
01:36
The energy of the photon...
