See the answer below.

Work Step by Step

Energy required by the atom is the same as the one provided by the photon: $E=h\times\nu$ $3.3\times 10^{-19}\ J=6.626\times10^{-34}\ J.s\times \nu$ $\nu=4.98\times10^{14}\ 1/s$ $c=\lambda\times\nu$ $\lambda=2.998\times10^8\ m/s\div4.98\times10^{14}\ 1/s$ $\lambda=6.02\times10^{-7}\ m=602\ nm$ This is in the visible spectrum with a reddish color.
