Particle Pair Production Aim : To acknowledge the mathematical and physical relationship present in a pair production lab experiment. Research Question: How do the different wavlength of a high energy photon raise the temperature of the area incident on a copper plate and therefore effect the velocity of the pair produced upon the the photon’s impact with the surface? Hypothesis: As the wavelength of the incident photon is varied, via a tuning laser, according to de Broglie’s wavelength the momentum of the photon will increase and so will the photon energy & surface temperature upon impact. With an increase in impact energy, the paired particle produced would correspondingly increase in kinetic energy therefore increase in velocity. Background information Natural phenomenon : If we consider a photon of very high energy, for example photons with frequencies of a gama ray and we assume it to hit a metal surface and correspondingly the nucleus of the atom. The interaction of the photon with the electromagnetic region of the nucleus leads to a spontaneous conversion of the the photonic energy into an electron and positiron pair. Concequently, it is important to note that the the pair production always occur as matter and anti-matter pair. Ofcourse, after the conversion of energy to matter, we can definitely expect the particles produced to have some sort of kinectic energy as it shoots out of the nucleus. This concept can infact be interpreted usigng the einstein’s famous equation E=mc 2 , where mass and energy are expressed as 2 different aspects of the same phenomenon. It turns out that this equation simply shows how the universe can change from one form to the other, through some incredible events. Hence, accorinding to this concept we can say, when an electron and positron meet up they will annihilate each other and turn right back to energy. Therefore, emphasizing on the process that givings rise to the idea of mass and energy being interchangeble.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
