29. The average frequency of light emitted by a 100-watt bulb is 5 x 1014 hertz. How many photons does that light bulb emit? (h= 6.63 x 10-34 J. s). 30. Electrons with a potential difference of about 10,000 volts are accelerated in a television screen tube. Find the maximum frequency of the X-rays that are emitted when these electrons hit the screen, slowing down.
