Answer:
Reflection-The throwing back by a body or surface of light, heat or sound without absorbing it is known as reflection.
Refraction-refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
