Photoelectric EffectHard
Question
A polychromatic light is used in an experiment on photoelectric effect. The stopping potential
Options
A.is related to the mean wavelength
B.is related to the longest wavelength
C.is related to the shortest wavelength
D.is not related to the wavelength.
Solution
eV0 = (KE)max = hν − hν0 = hc
