Two sinusoidal waves, identical except for phase, travel inthe same direction along a string, producing the net wavey(x, t) = (3.0 mm) sin(20x - 4.0t+ 0.820 rad), with x in metersand t in seconds.What are (a) the wavelength l of the two waves,(b) the phase difference between them, and (c) their amplitude ym?

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.
