A sinusoidal wave travelling in the positive x-direction is shown below. It has a frequency of3.00 Hz. Assume the diagram represents the wave at t = 0. Find the followinga) write a general expression for the wave function.b) amplitude (A)c) period (T)d) angular frequency (ω)e) wave number (k)f) wavelength (λ)g) speed of the wave (v).h) phase constant (ϕ).i) what is the value of the wavefunction when t = 1 sec and x = 25cm?
A wave is modeled by the wave function:
y (x, t) = A sin [ 2π/0.1 m (x - 12 m/s*t)]
1. Find the wavelength, wave number, wave velocity, period and wave frequency.
2. Construct on the computer, in the same graph, the dependence of y (x, t) from x on t = 0 and t = 5 s and the amplitude is A= 1.3m
3. After constructing the graph, make the appropriate interpretations and comments from the result that you got graphically.
4. How much is the wave displaced during the time interval from t = 0 to t = 5 s? Does it match this with the graph results? Justify your answer. Is the material transported long wave displacement? If yes, how much material is transported over time interval from t = 0 to t = 5 s? Comment on your answer. We now consider two sound waves with different frequencies which have to the same amplitude. The wave functions of these waves are as follows:
y1 (t) = A sin (2πf1t)
y2 (t) = A sin (2πf2t)
5. Find the resultant wave function analytically.
6. Study how the resulting wave…
