MCQ
Which one of the following does not represent a travelling wave
- A$y=\sin (x-v t)$
- B$y=y_m \sin k(x+v t)$
- C$y=y_m \log (x-v t)$
- ✓$y=f\left(x^2-v t^2\right)$
✓
Answer
Correct option: D.
$y=f\left(x^2-v t^2\right)$
(d) $y=f\left(x^2-v t^2\right)$ doesn't follows the standard wave equation.
