The following four waves are sent along strings with the same linear densities (x is in meters and t is in seconds). Rank the waves according to (a) their wave speed and (b) the tension in the strings along which they travel, greatest first: (1) y1 = (3 mm) sin(x - 3t), (2) y2 = (6 mm) sin(2x - t), (3) y3 = (1 mm) sin(4x - t), (4) y4 = (2 mm) sin(x - 2t).

Seiche
A seiche is an oscillating standing wave in a body of water. The term seiche pronounced saysh) can be understood by the sloshing of water back and forth in a swimming pool. The same phenomenon happens on a much larger scale in vast bodies of water including bays and lakes. A seizure can happen in any enclosed or semi-enclosed body of water.
