In 1924, de-Broglie proposed that every particle possesses wave properties with a wavelength , lambda given by lambda = h/(mv) where m is the mass of the particle, v is its velocity and h is Planck's constant. The de-Broglie prediction was confirmed experimentally when it was found that an electron beam undergoes diffraction , a phenomenon characteristic of waves. The de-Broglie wavelength can be estimated by measuring kinetic energy of an electron accelerating by a potential V as : 1/2 mv^2 = eV "where" 1eV = 1.6 xx 10^(-19) J, h = 6.6 xx 10^(-34) Js . The wavelength of particles constituting a beam of helium atoms moving with a velocity of 2.0 xx 10^4 ms^(-1) is
