What is the relationship between wave length and momentum of the particle?
According to De Broigle every body that is in motion has a wavelength associated with it and is given by the formula
Wavelength=h/mv
h-Plancks Constant
m-mass of the body
v-velocity of the body
And as
Momentum=p=mv
So we can write
Wavelength=h/p
Thank you :)
