Which of the following travelling wave will produce standing wave, with node at $x = 0$ , when superimposed on $y = A sin (ω t - k x)$ :

Options:

Answer:

Solution:

At $x = 0$ the sum must vanish for all $t$ : $A sin ω t + y_{2} (0, t) = 0$ , so $y_{2} (0, t) = - A sin ω t = A sin (ω t + π)$ . Hence $y_{2} = A sin (ω t + k x + π)$ .
