The cross section of this phenomenon is proportional to atomic number raised to the fifth.  One way to measure this phenomenon experimentally is to measure the stopping potential. This phenomenon is used for the function of night-vision goggles. A plot of the energy of this phenomenon graphed against frequency has an x-intercept at the threshold fr
The cross section of this phenomenon is proportional to atomic number raised to the fifth.  One way to measure this phenomenon experimentally is to measure the stopping potential. This phenomenon is used for the function of night-vision goggles. A plot of the energy of this phenomenon graphed against frequency has an x-intercept at the threshold frequency, a y-intercept at the negative work function, and a slope of Planck's constant. It was first demonstrated by Heinrich Hertz, and Einstein won a Nobel Prize for explaining it. For 10 points, name this effect in which electrons are ejected from a metal when light is shined on it.
