Classify mechanical waves accurately as either transverse or longitudinal.
Identify surface water ripples as a quintessential example of a transverse wave.
Identify sound waves travelling through the air as longitudinal waves characterized by areas of compression and rarefaction.
Describe the structural and behavioral differences distinguishing longitudinal and transverse waves.
Describe concrete evidence demonstrating that for both water surface ripples and sound waves, it is purely the wave energy moving, not the medium (water or air) itself.
