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$y = {y_m}\log (x - v\,t)$
- ✓$y = f({x^2} - v\,{t^2})$
✓
Answer
Correct option: D.
$y = f({x^2} - v\,{t^2})$
d
(d) $y = f({x^2} - v{t^2})$ doesn’t follows the standard wave equation.
(d) $y = f({x^2} - v{t^2})$ doesn’t follows the standard wave equation.
