A hypothetical atom has three energy levels: the ground level and the 1.0 eV and 3.0 eV above the ground level. I.) Find the frequencies and wavelengths of the spectral lines that this atom can emit when excited then state the region of spectrum they can be found ii.) What wavelengths can be absorbed by this atom if it is initially in its ground level?

Aball thrown by ginger is moving upward through the air. diagram a shows a box with a downward arrow. diagram b shows a box with an upward arrow. diagram c shows a box with a downward and upward arrow equal in size. diagram d shows a box with a downward and upward arrow with the downward arrow larger in size. which force diagram represents the forces on the ball? you may neglect the effects of air resistance.
