| definition | A tiny particle or bundle of radiant energy. | 
| eg_sentence | The idea that light consists of photons is difficult until you begin to think of a ray of light as being caused by a stream of tiny particles. | 
| explanation | It was Albert Einstein who first theorized that the energy in a light beam exists in small bits or particles, and scientists today know that light sometimes behaves like a wave (somewhat like sound or water) and sometimes like a stream of particles. The energies of photons range from high-energy gamma rays and X-rays down to low-energy infrared and radio waves, though all travel at the same speed. The amazing power of lasers is the result of a concentration of photons that have been made to travel together in order to hit their target at the same time |
