A)
B)
C)
D)
Correct Answer: D
Solution :
Key Idea: Compare the Einsteins photo- electric equation with the equation of straight line. Einsteins photoelectric equation is \[KE=hv-\phi \] ...(i) where\[\phi =\]work function of metal Comparing above Eq. (i) with equation of a straight line \[y=mx+c\] we get \[m=h,c=-\phi \] Therefore, if we draw a graph between kinetic energy and frequency, then a straight line cutting the frequency axis at\[{{v}_{0}}\]and giving an intercept of (-(|)) on the kinetic energy axis, is obtained.You need to login to perform this action.
