Questions
In a photoelectric experiment, when energy of photon of incident radiation is 6.5 eV, the stopping potential is found to be 3 V. In the same experimental set up, what will be the wave length of incident radiation, if the stopping potential is 2 V ?
detailed solution
Correct option is A
Work function of target metal =6.5-3=3.5 eVWhen stopping potential is 2 volt, energy of each photon of incident radiation 3.5+2=5.5 eVWave length of incident radiation =124205.5 Ao=2258 AoTalk to our academic expert!
