According to the de-Broglie, every particle has a wave associated with it. The wavelength of the wave is inversely proportional to the momentum of the particle.

wavelength = plank's constant/ momentum

Wavelength = h/ p

p= momentum= mass x velocity= mv

wavelength= h/mv

v= h/ m x wavelength

mass=9.1 x 10

h= 6.67 x 10

wavelength= 0.32 nm = 0.32 x 10

speed= 6.67 x 10

speed= 2.3 x 10
