Reflection
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Example: of reflection is light, sound and water waves.

Refraction
Refraction: the change in direction of a wave passing from one medium to another caused by its change in speed. Example: waves in deep water travel faster than in shallow

Diffraction
Diffraction: A bending of waves around obstacles and openings
Example: The radio waves bend around the building and the reception is still good on the opposite side

Constructive Interference
Constructive interference: is the interference of two or more waves of equal frequency
Example: loud areas from speakers (sound waves).
constructive interference
Destructive Interference
Destructive Interference: Is the interference of two waves of equal frequency with opposite phase.
Example: Noise canceling headphones (sound waves)
destructive interference
Resonance
Resonance: when one object vibrating at the same natural frequency of a second object forces that second object into vibration motion.
Example: acoustic resonances of musical instruments and our vocal cords
Resonance
Doppler Effect
Doppler Effect: is the change in frequency of a wave for an observer moving relative to its source.
Example: When an emergency vehicle passes by you it's frequency of the sirens are higher than normal when it passes you and then moves away.
The Doppler Effect: what does motion do to waves?
Beats (sound waves only)
Beats: an interference pattern between two sounds of slightly different frequencies.
