Q-9 A harmonic plane wave in a water pond is moving in a particular direction that we can call x-axis. The wave has an amplitude of 0.5 m and a wavelength of 0.25 m whereas its speed is 2 m/s. What is the angular frequency and angular wave number of this wave? How many waves fit in a length of 10 m. Suppose at t= 0 there is a full peak at x = 0. What is the height of water at x = 2 m and x = 2.1 m at this time? What is the height at these same points at t= 1 s?
