De Broglie wavelength is:

$\overline{){\mathbf{\lambda}}{\mathbf{=}}\frac{\mathbf{h}}{\mathbf{m}\mathbf{v}}}$, where h is the Plank's constant, v is the speed, and m is the mass of a proton.

Calculate the de Broglie wavelength for a proton moving with a speed of 7x10^{6} m/s. The mass of a proton is 1.67262 x 10^{-27} kg and Planck’s constant is 6.62607x10^{-34} J•s. Answer in units of m.
