Reflection: When a light ray strikes a smooth shiny surface, after striking it bounces back, this phenomena is called Reflection of light.
Refraction: When a light ray enters from one medium (e.g Air) to another medium (e.g Glass) it deviates from its original path bends into the denser medium.
Due to reflection light spreads out just before the sun rise.
Due to refraction objects placed into water shows false position then their correct position.
