What is the wavelength (in meters) of a 0.5 kg particle moving with a velocity of $6.63×{10}^{-34}m/s$?
HINT: Use de Broglie equation with the plank constant in units of $J\cdot s\left(h=6.63×{10}^{-34}Js\right)$

Given data:
Mass $\left(m\right)=0.5kg$
Velocity $\left(v\right)=6.63×{10}^{-34}m/s$
$h=6.63×{10}^{-34}J.s$
Required:
Wavelength ($\lambda$)
The de Broglie wavelength is given by
$\lambda =\frac{h}{mv}\phantom{\rule{0ex}{0ex}}=\frac{6.63×{10}^{-34}J.s}{\left(0.5gk\right)\left(6.63×{10}^{-34}m/s\right)}\phantom{\rule{0ex}{0ex}}=2m$
The wavelength of the particle is 2 m
