According to de-broglie equation :-

λ = h/mv

or λ = h/p

p = momentum

λ = wavelength

h = planck's constant ,

Now let us derrive it :-

let us consider a particle say(photon) whose energy is given by , E = hν , let us compare it with E = mc²

hν = mc²

hc/λ = mc²

λ = h/mc or λ = h/mv

It gives relation between wavelength , mass & velocity of a particle
