A light is shining on a metal surface, ejecting electrons. If you increase the intensity:r of light more electrons are ejected each second. both more energetic electrons are eject each second, and more of them are ejected each second. protons may also be ejected each second. more energetic electrons are ejected each second. \fPhoton, the particle of light, canies energy and momentum. has no wave properties. cam'es both positive and negative charges. is 1DD times lighter than an electron
