MOTION PICTURE PROJECTION 119 air by the vibrations of bodies of ordinary dimensions, so light waves are disturbances set up in the ether probably by the vibrations of the minute corpuscles or electrons, of which the atoms of ordinary matter are supposed to be built up. Since these corpuscles are extremely small in comparison with ordinary bodies it is not surprising that their rates of vibration are enormously larger than the vibration rates of tuning forks, or other bodies which send out sound waves. Just how these corpuscles are set into vibration and in just what manner they vibrate, we cannot say as yet with certainty, but since we do know that an increase in the temperature of all bodies means an increase in the agitation of the molecules and atoms of which these bodies are composed. It is not surprising that the vibrations which communicate light waves to the ether take place in general in bodies which have a high temperature and that the hotter the body becomes the more intense becomes the light waves which it emits. i Snaplite Lens
