Question

The figure shows graph between stopping potential (along y-axis) and incident frequency (along x-axis) for different target metal A,B,C and D. Let ϕA,ϕB,ϕCandϕDare the work function of different target metals A,B,C and D respectively Then the correct rank of work function of different target metals is

Solution

The correct option is B ϕA>ϕB>ϕC>ϕD
The Einstein's photoelectric equation in terms of stopping potential is eVs=hνϕ
or Vs=hνeϕ/e
Thus, it will represent a straight line and intercept is ϕ/e
From the graph we can write, ϕA/e>ϕB/e>ϕC/e>ϕD/e
or ϕA>ϕB>ϕC>ϕD
