Question

Find the de Broglie wavelength of a particle with mass of 6.4×10-27 kg and velocity of 2×108 m/s?

Answer 1

`5.18 × 10^-16\ "m"`

Explanation:

de-Broglie wavelength is given by

`λ = h/(mv)`

`λ = (6.626 × 10^-34\ "m"^2"/kg s")/(6.4 × 10^-27\ "kg" × 2 × 10^8\ "m/s") = 5.18 × 10^-16\ "m"`
