11.Dual Nature of Radiation and matter
easy
According to Einstein's photoelectric equation, the graph between the kinetic energy of photoelectrons ejected and the frequency of incident radiation is
A
B
C
D
(AIPMT-1996) (AIPMT-2004)
Solution
(d)According to Einstein equation
$h\nu = h{\nu _0} + {K_{\max }}$
==> ${K_{\max }} = h\nu – h{\nu _0}$ on comparing it with $y = mx + c,$ it is clear to say that,
This is the equation of straight line having positive slope $(h)$ and negative intercept $(h{\nu _0})$ on $KE$ axis.
