Question:medium
Photons of \(5.5\ \mathrm{eV}\) energy fall on the surface of the metal emitting photoelectrons of maximum kinetic energy \(4.0\ \mathrm{eV}\). The stopping voltage required for these electrons is
Photons of \(5.5\ \mathrm{eV}\) energy fall on the surface of the metal emitting photoelectrons of maximum kinetic energy \(4.0\ \mathrm{eV}\). The stopping voltage required for these electrons is
Show Hint
Stopping potential is independent of light intensity and depends only on frequency.
