Question

The maximum kinetic energy of the photoelectrons depends only on

• A. Potential
• B. Frequency
• C. Incident angle
• D. Pressure

Answer 1

The correct option is B Frequency

Maximum kinetic energy of photoelectrons $K.E_{max}=h\nu -\varphi$

where $\nu$ is the frequency of incident photon and $\varphi$ is the work function of metal

Hence maximum kinetic energy of photoelectrons depends only on the frequency of the incident photons.
