Calculate the wavelength (in nanometer) associated with a proton moving at 1.0 x 10³ ms⁻¹ (Mass of proton = 1.67

\times

10^-27 kg and h = 6.63

\times

10^-34 Js) :

Accepted Answer

Wavelength

(λ)

=

\frac{h}{m v}

=

\frac{6.63 \times 10^{- 34}}{1.67 \times 10^{- 27} \times 10^{3}}

= 0.4

\times

10^-9

= 0.4 nm
