A photon of wavelength l is scattered from an electron, which was at rest. The wavelength shift \[\Delta \lambda \] is three times of \[\lambda \] and the angle of scattering \[\theta \] is \[60{}^\circ \]. The angle at which the electron recoiled is \[\phi .\] The value of tan \[\phi \] is : (electron speed is much smaller than the speed of light)
