Answer» Reflection: The bouncing back of rays of light from a polished and shiny surface is called reflection or reflection of light. It is similar to bouncing back of a football after colliding with a wall or any hard surface.Refraction of light: When travelling obliquely from one medium to another, the direction of propagation of light in the second medium changes.
