The work function of aluminium is 
. If two photons each of energy 
strike an electron of aluminium, then emission of electron will
Text Solution
Verified by ExpertsThe correct answer is:
C
Work function of aluminium is 
. The energy of two photons can not be added at the moment photons collide with electron all its energy will be dissipated or wasted as this energy is not sufficient to knock it out. Hence emission of electron is not possible.
