Define Transmission, reflection, refraction and diffraction

transmission:  the act or process by which something is spread or passed from one person or thing to another

reflection: when light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Smooth, shiny surfaces such as mirrors and polished metals reflect light well.

refraction: change in direction of a wave passing from one medium to another or from a gradual change in the medium

diffraction: various phenomena that occur when a wave encounters an obstacle or opening
