A sinusoidal wave is traveling on a string with speed 45.8 cm/s. The displacement of the particles of the string at x = 18 cm is found to vary with time according to the equationy = (1.7 cm) sin[1.1 - (2.8 s-1)t].The linear density of the string is 9.3 g/cm. What are (a) the frequency and (b) the wavelength of the wave? If the wave equation is of the formy(x,t) = ym sin(kx - ωt),what are (c) ym, (d) k, and (e) ω, and (f) the correct choice of sign in front of ω? (g) What is the tension in the string?

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.
