A photon of wavelength 1.4 Å collides with an electron. After collision, the wavelength of the photon is found to be 2.0 Å. Calculate the energy of the scattered electron.


Correct option is


Energy of the photon before collision = hv 

Energy of the photon after collision = hv’   

Difference of energy is imparted to the electron.  

Hence, energy of the scattered electron
