When a wave is refracted, Group of answer choices it enters a new medium or material and the wave bends and changes speed. An example is how a straw looks bent in a glass of water. it bounces off a surface, like when you see yourself in the mirror. its waves have gotten bunched up and the frequency is higher, like when an ambulance is coming towards you with its sirens on, it has a higher pitch. it has encountered a barrier and is bent around it. An example is when you can hear someone through an open doorway but you cannot see them.
