The maximum kinetic energy of emitted electrons in a photoelectric effect does not depend upon
- A wavelength
- B frequency
- C intensity
- D work-function
Answer & Solution
Correct Answer
(C) intensity
Step-by-step Solution
Detailed explanation
According to Einstein's photoelectric equation maximum kinetic energy, \[ \begin{aligned} K_{\max } &=e V_{0}=h v-\phi_{0} \\ &=h\left(v-v_{0}\right)=h c\left(\frac{1}{\lambda}-\frac{1}{\lambda_{0}}\right) \end{aligned} \] Hence, in photoelectric effect, maximum kinetic energy…
