Verified by Toppr
The photoelectric effect related with the incident light frequency (ν) by the following equation: Ek=eVs=hν−ϕ, where, ϕ=hν0 is the work function of the material and Ek is the kinetic energy of the photo electron. So, Ek=hν−hν0, ν0 is the threshold frequency for the metal. or, Ek=h(ν−ν0). So the kinetic energy of photoelectrons depends on the difference of threshold frequency and frequency of incident light.
So, the answer is option (C).
