quantum atom and atomic spectra

in the electromagnetic spectrum which  of the following types of radiation has less energy than visable light?    ultra violet, gamma rays, x reays microwaves

2.which of the following colors of light has the highest energy blue, green, vilolet, red

3. what happens when an electron falls to a lower energy level?  the electron absorbs energy,  the electron takes on a lower frequency, the electron releases energy, the electron takes on a higher frequency

4, planck’s equation e=hxv isused to determine ? the color of the lines on the atomis spectrum for an atom, the energy released as an electron moves to a lower orbital, the energy released as an electron moves to a higher orbital, the number of lines on the atomic spectrum for an ato.
