H2 Physics · JC 2 · Easy · Emission and absorption spectra
Light of wavelength is incident on a photocell and causes a current. The lamp is then moved so that its distance from the photocell is doubled. Assuming no other changes, what happens to the rate of emission of photoelectrons?
- It becomes one quarter of the original rate.
- It becomes one half of the original rate.
- It remains unchanged.
- It becomes one eighth of the original rate.
