Q)

Calculate the wavelength (in nanometer) associated with a proton moving at a velocity $1.0\times10^3ms^{-1}$ (mass of proton =$1.67\times10^{-27}kg \;and\; h = 6.63\times10^{-34}Js)$

$\begin{array}{1 1}(a)\;0.032\;mn\\(b)\;0.40\;nm\\(c)\;2.5\;nm\\(d)\;14.0\;nm\end{array}$

A)
Wave length
$\lambda = \frac{h}{mv}$
$=\large\frac{6.63\times10^{-34}}{1.67\times10^{-27}\times10^3}$
=0.4nm
