\mathrm{E=11 \mathrm{eV}=11 \times 1.6 \times 10^{-19} \mathrm{~J}=h v}

Or \mathrm{v=\frac{11 \times 1.6 \times 10^{-19}}{h}=\frac{11 \times 1.6 \times 10^{-19}}{6.62 \times 10^{-34}}}

                                                    \mathrm{=2.65 \times 10^{15} \mathrm{~Hz}}

This frequency radiation belongs to ultraviolet region.
