Statement-1: Work function of aluminum is \( 4.2 \mathrm{eV} \). If two photons each of energy \( 2.5 \mathrm{eV} \) strikes on a piece of aluminum, the photo electric emission does not occur.
\( P \)
Statement-2 : In photo electric effect a single photon interacts with a single electron and electron is emitted only if energy of each incident photon is greater then the work function.
W.
