  • Velocity=v=40m/s
  • Wavelength=\lambda
  • Mass of proton=1.67×10^{-27}Kg

We know

\boxed{\sf \lambda=\dfrac{h}{mV}}

\\ \sf\longmapsto \lambda=\dfrac{6.626\times 10^{-34}}{1.67\times 10^{-27}\times 40}

\\ \sf\longmapsto \lambda=158.7\times 10^{-7}m

\\ \sf\longmapsto \lambda=15.8\times 10^{-6}m

\\ \sf\longmapsto \lambda=15.8\mu m
