The Vibrations on the top interfere with the water.
Reflection: When an some sort of object is thrown against a wall it bounces back. This "reflection" of the object can be shown in terms of momentum and energy conservation. If the collision between ball and wall is perfect, then all the incident energy and momentum is reflected, and the ball bounces back with the same speed. If the collision is inelastic, then the wall (or ball) absorbs some of the incident energy and momentum and the ball does not bounce back with the same speed.
Refraction: The wave will refract as it passes through a material, its direction might change from its original path but will still pass through.
Diffraction:Various things that occur when a wave encounters an obstacle. for instant's the material bending waves around small obstacles and the spreading out of waves past small openings.
