The work function for nickel is 5.15 eV.
(a) Convert the value of the work function from electron volts
to joules.
J
(b) Find the cutoff frequency for nickel.
Hz
(c) What maximum wavelength of light incident on nickel releases
photoelectrons from the nickel's surface?
nm
(d) If light of energy 7.12 eV is incident on nickel, what is the
maximum kinetic energy of the ejected photoelectrons? Give the
answer in electron volts.
eV
(e) For photons of energy 7.12 eV, what stopping potential would be
required to arrest the current of photoelectrons?
V
In this question we have to find different parameters using the concepts of Photoelectric effect.
