A) the work function of the mental is eb.
B) the work function of the metal is ea.
C) the value of Planck's constant is equal to \[\frac{2eb}{a}\]
D) the value of Planck's constant is equal to \[\frac{ea}{b}\]
Correct Answer: A
Solution :
The relation between the stopping potential and the frequency is \[hv=e{{V}_{s}}+\phi \]or \[{{V}_{S}}=\frac{h}{e}v-\frac{\phi }{e}\] From the graph y intercept = b \[\therefore \] \[b=\frac{\phi }{e}\Rightarrow \phi =be\] Hence, the correction option is [a].You need to login to perform this action.
