There are two very small natural particle which are held fixed at a separation of 1 m from each other . Using some mechanism , one electron is transferred from particle to the other and electric potential energy lost in this process is converted into a photon of wavelength lamda_1 . When one more electron is transferred in the same direction , the wavelength of photon emitted is lamda_2 . If lamda_1 -lamda_2=5^pxx23^q calculate the value of pq. {:(0,1,2,3,4,5,6,7,8,9):}
