Q.
For the photoelectric effect, the maximum kinetic energy ( $E_{k}$ ) of the photoelectrons is plotted against the frequency ( $v$ ) of the incident photons as shown in the figure. The slope of the graph gives [2024]

1 Ratio of Planck’s constant to electric charge

2 Work function of the metal

3 Charge of electron

4 Planck’s constant

Ans.
(4)

We know that

$E = K . E . + ϕ_{0}$

$h ν = K . E . + ϕ_{0}$

$K . E = h ν - ϕ_{0}$

Slope of kinetic energy versus frequency curve will be equal to slope $h .$
