An atom emits energy equal to 4 x 10^-12 erg. To which part of electromagnetic spectrum it belongs ?

Find $\mathrm{\lambda }$ from $\mathrm{E}=\frac{\mathrm{hc}}{\mathrm{\lambda }}$; It comes out to be 4965 $\stackrel{\mathrm{o}}{\mathrm{A}}$, which represents visible region (i.e., in between  3800 - 7600 $\stackrel{\mathrm{o}}{\mathrm{A}}$).
