2. The hydrogen atom absorbs a photon of visible light causing it's one electron to move from the \( n=2 \) level to the \( n=4 \) level. Calculate the change in energy of the atom. Calculate the wavelength (in \( \mathrm{nm} \) ) of the photon. What part of the electromagnetic spectrum is the wavelength in? Can you determine the color of the wavelength? Has the atom absorbed or emitted light? \( \Delta E=-2.18 \times 10^{-18} \mathrm{~J}\left(1 / n^{2},-1 / n^{2}\right. \) i \( ) \)
