The work function of Silver and sodium a...

The work function of Silver and sodium are `4.6 and 2.3 eV, ` respectively . The ratio of the slope of the stopping potential versus frequency plot for silver to that of sodium is

Text Solution

Verified by Experts

The correct Answer is:
1
`eV_(x)=hv-phiimplies V_(S)=(h/e)v-phi/e`

`implies` slope `=h/e=` constant `implies` ratio `=1`
