What is the maximum wavelength of incident light that can produce photoelectrons from silver? The work function for silver is Φ=2.93 eV. (in nm)

Wavelength of 424 nm  can produce photoelectrons from silver

Explanation:

= work function = energy of photon

h = Planck's constant =  

= frequency of the metal

c = speed of light =  

=longest  wavelength of the radiation

Now put all the given values in the above formula, we get the wavelength of the photons.

     ( as 1ev= )

Here, wavelength of 424 nm  can produce photoelectrons from silver
