This Photo-Electrict Tube, designed to measure the speed of electrons knocked loose from an clement by invisible ultra-violet light, can best be explained by terms in baseball, according to research scientists. The actions take place in the tube’s black sphere. Using a beam of ultra-violet light, as a “bat” the scientists knock electrons from an element suspended in the sphere’s centre and measure the speed with which they hit the “outfield,” the sphere’s inner surface. By means of delicate electronic measuring instruments, as few as 6000 electrons a second (one quadrillionth of an ampere) can be detected hitting the “outfield.”
