de-Broglie’s hypothesis states value of a wavelength associated with a particle of mass m which is moving with speed v.
The formula for de-Broglie’s hypothesis is given as,
Wavelength = Planck’s constant / momentum
λ = h / p…………………..(1)
We know that momentum = mass × velocity
substituting value of p in (1) we get,
λ = h / mv
λ = wavelength h = Planck’s constant
p = momentum m = mass
v = velocity
