Energy Pair Pair production Photon Wavelength

AI Thread Summary

In pair production, an electron and positron with 220 keV of kinetic energy each can produce a photon. The total energy required for this process is 1.46 MeV, which includes the rest mass energy of the electron and positron. The corresponding wavelength of the photon produced is calculated to be 8.49 x 10^-13 meters. Understanding the relationship between energy and wavelength is crucial for solving these types of problems. The collision of the electron and positron results in the creation of a photon, demonstrating the principles of particle-antiparticle interactions.

Homework Statement

Electron and positron each have a kinetic energy of 220 keV even when far apart.

Homework Equations

The Attempt at a Solution

I have no idea. My book says the answer 1.46 MeV, 8.49 x 10^-13 m but I don't know how to get that.

Position is antiparticle of electron. So what will happen when they collide?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
