From the De Broglie equation,
λ = h/p
=> p = h/λ
=> mv = h/λ
=> v = h/(λm)
Put in the values of h (planck's constant), λ (given wavelength) and m (mass of an electron)
λ = h/p
=> p = h/λ
=> mv = h/λ
=> v = h/(λm)
Put in the values of h (planck's constant), λ (given wavelength) and m (mass of an electron)
