When light of wavelength $\lambda$ illuminates a copper surface, the stopping potential is $V$. In terms of $V$, what will be the stopping potential if the same wavelength is used to illuminate a sodium surface?

Step 1
The energy of the ejected electrons is determined by the energy of the incoming light and the work function of the metal, which is the minimum energy required to remove an electron from the surface of the metal. The energy of the incoming light is given by the Show more…

When light of wavelength λ illuminates a copper surface, the stopping potential is V. In terms of V, what will be the stopping potential if the same wavelength is used to illuminate a cobalt surface? (Use the following as necessary: V.)

A metal surface has a photoelectric cutoff wavelength of $325.6 \mathrm{nm}$. It is illuminated with light of wavelength $259.8 \mathrm{nm}$. What is the stopping potential?
When a certain photoelectric surface is illuminated with light of different wavelengths, the following stopping potentials are observed: Plot the stopping potential on the vertical axis against the frequency of the light on the horizontal axis. Determine (a) the threshold frequency; (b) the threshold wavelength; (c) the photoelectric work function of the material (in electron volts); (d) the value of Planck's constant $h$ (assuming that the value of $e$ is known).
