Answer

See the answer below.

Work Step by Step

a) The 253.62 nm is the most energetic because it has a lower wavelength (higher frequency). b) $c=\lambda\times\nu$ $\nu=2.998\times10^8\ m/s\div 253.652\ times10^{-9}\ m=11.82\times10^{14}\ 1/s$ $E=h\times\nu$ $E=6.626\times10^{-34}\ J.s\times 11.82\times10^{14}\ 1/s=7.83\times10^{-19}\ J$ c) 404.656 and 435.833 nm are present, both with a blue color.
