Question

In column I some physical quantities are given. Match the appropriate expression choosing from Column II

Answer 1

A> $\lambda =\frac{h}{p}=\frac{h}{mV}$
B> $E=hV=\frac{hC}{\lambda }$
C> $K_{max}=hV-\varphi =\frac{hC}{\lambda }-\frac{hC}{{\lambda }_0}$
D> $eV=\frac{hC}{\lambda }$ [energy balance]
$\Rightarrow \lambda =\frac{hC}{eV}$ [V is PD across the tube]
