Answer to Question #303447 in Molecular Physics | Thermodynamics for lamo

Question

An electron and a positron are moving side by side in the +x direction at 0.500c when they annihilate each other . Two photons are produced that moves along the x axis (a) Do both photons move in the +x direction ? (b) What is the energy of each photon

Answer 1

Answer

Electron and proton are moving in x-direction at .$1.5 * 10^8m/s$

They annihilate each other, two photons. produced that move along the x-axis.

2.Annihilation occurs when a particle and a Corresponding antiparticle meet and their mass is converted into radiation energy.

a) Two photons produce in the process when no outside force actin

g on it,then both beton would have momentum.

b) The minimum energy of each photon is given by $h\nu_{min}$ to the rest energy of the positron and g the electron.

-: Minimum energy of each photon produced, $h\nu_{min}$ = E ₀(fo is rest energy of the electron)

Both more in positive direction along x-axis.
