In an accelerator experiment on high-energy collisions of electrons with positrons, a certain event is interpreted as annihilation of an electron-positron pair of total energy 10.2 Bev into two gamma-rays of equal energy. What is the wavelength associated with each gamma-ray? ("1Bev = "10^(9) eV)

Answer»

Solution :USE `LAMBDA=(hc//E)" with " E=5.1xx1.602xx10^(-10)J" to get "lambda=2.43xx10^(-16)m`.
