1. The spectrum of white light doesnt have all possible frequencies. (T/F)
2.The energy of a photon is inversely proportional to its frequency.(T/F)
3.What is the energy of a photon with frequency of 2x1014Hz? h=6.6x10-34J.s
4. An electron jumps from the third level to the first level in hydrogen atom. What is the energy of the emitted photon?
