If critical wavelength of a metal surface is 2000

Question

If critical wavelength of a metal surface is 2000 angstrom . Then find the wavelength of photon which emit photoelectrons with kinetic energy maximum twice of those produce at 1500 angstrom

Piyush · Accepted Answer

Threshold wavelength is 2000 angstromBy using formula E=h×v E is 9.939×10^-19Energy produced by wavelength of 1500 angstrom is 13×10^-19So kinetic energy is 4.1×10^-19J Twice kinetic energy is equal to 8.2×10^-19JTotal energy become 18.1×10^-19JCorresponding wavelength to the energy is 1.1×10^-19
