While considering the equilibrium between matter and radiation, Einstein found that the usual absorption and emission (now called, spontaneous emission) process

Verschachtelte Anfragen in SQL,In the Huygens theory, the light appears to travel in a straight line. However, when a wave encounters an obstacle (or an opening), it bends around the edges of the obstacle (or opening). This phenomenon of bending of wave (light) around an edge of the obstacle (or opening) is known as the ..
