Fact of the Day
Laser stands for 'Light Amplification by Stimulated Emission of Radiation'. A laser beam is produced when light bounces back and forth between two mirrors with a special medium (gas, liquid, or solid) between them. As it bounces, the light triggers energized atoms in the medium to release more light, some of which leaks out through one of the mirrors to produce the laser beam.Word of the Day
