Teaching UKPSC Lecturer Mock Test Series 2024 Physics Dual Nature: Photon and Matter Waves The Photoelectric Effect
When the energy of incident radiation is increased by 20%, the kinetic energy of the photo electrons emitted from a metal surface increased from 0.5 eV to 0.8 eV. The work function of the metal is
1
0.65 eV
2
1.0 eV
3
1.3 eV
4
1.5 eV
