Consider a helium (He) atom that absorbs a photon of wavelength 330 nm. The change in the velocity (in cm s\(-\)1) of He atom after the photon absorption is __________.
(Assume : Momentum is conserved when photon is absorbed.
Use : Planck constant = 6.6 \(\times\) 10\(-\)34 J s, Avogadro number = 6 \(\times\) 1023 mol\(-\)1, Molar mass of He = 4 g mol\(-\)1)
