Maximum Wavelength

Postby MaryBanh_2K » Thu Nov 07, 2019 9:48 am

How do you find the maximum wavelength in which an electron can be ejected?

I don't think you can find the maximum wavelength. however, you can find the minimum wavelength by equating the energy of the light to the work function and solving for wavelength using the speed of light.

I agree with the answer above, but shorter wavelengths have more energy so I'm assuming by "maximum wavelength" they mean the longest and least energy wavelength it would take to eject an electron.
