1.Beta-carotene absorbs primarily blue and violet light in the visible spectrum. 
Explain why it appears orange.  Do you see the light that is absorbed?
What do you see instead

2.Molecular vibrational transitions absorb infrared radiation, while electronic transitions of double bonds absorb ultraviolet radiation. Use Figure 7.5 in Ebbing, along with the equations E=hc/ and E=h, to explain how the energies of infrared and ultraviolet compare with visible light transitions. 
That is, do they have higher or lower energies than visible light?


3.Suppose an atom absorbs a photon and undergoes a quantized transition from a lower energy level to a higher energy level.  Explain how you would mathematically determine the energy and frequency of the photon.  That is, explain the concept of  E for the two energy levels.
