Question

 

In an accelerator experiment on high-energy collisions of the electrons with positrons, a certain event is interpreted as the annihilation of an electron-positron pair of total energy 10.2 BeV into two -rays of equal energy. Find the wavelength associated with each -ray. 

Solution

Correct option is

The energy of each -ray photon is

      

          

            

          

Therefore, the wavelength associated with each -ray is 

              

                  

                  .
