14. Because violet light has more energy than red light,
A. red light is less bright than violet light.
B. violet light has a higher wave frequency than red light.
C. the mass properties of light are invariable.
D. violet light is preferable in a photographer's darkroom.

Answer:B. violet light has a higher wave frequency than red light.Explanation:The energy of a light wave is directly proportional to its frequency, according to the relationship:[tex]E=hf[/tex]whereE is the energy of the waveh is the Planck constantf is the frequency of the waveThe problem tells us that violet light has more energy than red light: since energy and frequency are directly proportional, this also means that violet light has higher frequency than red light, so the correct choice isB. violet light has a higher wave frequency than red light.

I think the answer should be B. Since the energy has to do with the frequency. The higher the energy, the higher the frequency.
