List of top Physics Questions on Photoelectric Effect asked in VITEEE

The collector plate in an experiment on photoelectric effect is kept vertically above the emitter plate. Light source is put on and a saturation photo-current is recorded. An electric field is switched on which has a vertically downward direction, then

The work function of a certain metal is \(3.31 \times 10^{-19}\,J\). Then, the maximum kinetic energy of photoelectrons emitted by incident radiation of wavelength \(5000\,\AA\) is (given \(h = 6.62 \times 10^{-34}\,Js\), \(c = 3 \times 10^8\,m\,s^{-1}\), \(e = 1.6 \times 10^{-19}\,C\))

A light whose frequency is equal to \(6 \times 10^{14}\) Hz is incident on a metal whose work function is 2 eV. The maximum energy of the electrons emitted will be

A photo-sensitive material would emit electrons if excited by photons beyond a threshold. To overcome the threshold, one would increase

The de Broglie wavelength associated with a steel ball of mass 100 g moving at a speed of 1 m/s is:
