Problem

Which expression gives the de Broglie wavelength

\lambda

of a non-relativistic particle of mass

m

moving with speed

v

? a)

\displaystyle \lambda=\dfrac{2h}{m v}

\displaystyle \lambda=\dfrac{h}{2\pi m v}

\displaystyle \lambda=\dfrac{h}{m v}

\displaystyle \lambda=\dfrac{h}{\gamma m v}
