6. What is the energy of a quantum of light with a frequency of 6.17 x 10 14 Hz
7. Solar panels rely on light's ability to remove electrons from the surface of the solar cell. The energy required to release an
electron from atoms on the surface of the cell is 6.7 x 10 -19 J. What wavelength of light would be necessary for electrons to
leave the cell's surface and return to the surface to produce the energy (used as electricity)
