Question

Proton moving at 3.97 X 10 8 m/s (mass of a proton = 1.673 x 10 -27 kg) what is its wavelength in nm??

Answer 1

The wavelength of the proton is9.9 * 10⁻⁷ nm.

What is the wavelength of the proton?

The wavelength of a particle or wave is the distance between successive point in phase in the particle or the wave.

It can be said to be distance between successive crests or troughs.

The wavelength of a moving particle is given by the De Broglie's equation as follows:

• λ = h/mv

where h is Planck's constant = 6.63×10⁻³⁴ Js

m = mass of particle = 1.673 x 10⁻²⁷ kg

v is velocity of proton = 3.97 x 10⁸ m/s

λ = 6.63×10⁻³⁴/1.673 x 10⁻²⁷ * 3.97 x 10⁸

λ = 9.9 * 10⁻⁷ nm
