4. (a) Write down an equation of a travelling wave moving along + x axis and define each term. Can you also define the velocity of the travelling wave? (b) A travelling wave on a string is described by the displacement equation y(x, t) = 0.01 m Sin (2??/3.0 x + 2??/6.0 t - ?/3), where x is in m and t is in s. I) Find the wavelength, frequency and speed of the wave. II) In which direction is the wave travelling? If the wave is travelling in the opposite direction, can you rewrite the wave equation? III) Draw a displacement versus time graph for a point located at x=0.5 m for t=0 s and t=2.0 s.

Step 1

01 \, \text{m} \) is the amplitude of the wave, - \( k = 2\pi \) is the wave number, - \( \omega = 2\pi f \) is the angular frequency, and - \( f \) is the frequency of the wave. The velocity of the travelling wave is given by \( v = \frac{\omega}{k} \). Show more…
