What is a Gamma Ray Wavefront?

Gamma Ray Wavefronts
When a gamma ray interacts with the atmosphere the particles produced continuedownward toward the Earth's surface. As they continue to interact, theparticles are slowed down. Thus, not all of the particles emitted in a showerare going to reach the earth at the same time. The wavefront of the shower isthe way the shower would look if you could see every photon at the same time. For our purposes, we looked at wavefronts on a two dimensional scale. Time waspresented on the y-axis and displacement on the ground was represented on thex-axis.
