Answer the following question given this paragraph: 

Most waves approach the shore at an angle. The part of the wave that is nearer the shore reaches shallow water sooner than the part that is farther out. The shallow part of the wave "feels" the bottom first. This slows down the inshore part of the wave and makes the wave "bend. " This bending is called refraction .


Q: What three characteristics do waves have?


A:
reflection, refraction and deflection
