Question

Maximum kinetic energy of the emitted photoelectrons depends upon

• A. Intensity of incident light
• B. Frequency of incident light
• C. Total number of photons of incident light
• D. Both (2) and (3)

Answer 1

The correct option is B Frequency of incident light

We know,

By photoelectric equation,

$\frac{hc}{\lambda }-\varphi =K{E}_{max}$

$h\upsilon -\varphi =K{E}_{max}$

It is clear that,

Maximum Kinetic energy depends upon the incident frequency.

Option $\text{B}$ is the correct answer
