A sinusoidal wave on a string travels to the right. The wave has the following characteristics: wavelength = 2.05 m, amplitude = 0.100 m, and speed = 1.25 m/s. Assume that at t = 0, the left end of the string is at the origin and its transverse velocity is negative. (a) Find the frequency (in Hz) for this wave. (b) Find the angular frequency (in rad/s) for this wave. (c) Find the angular wave number (in rad/m) for this wave.

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.
