$y = f(x^2 - vt^2)$

Vedclass · Answer

(D) travelling wave must be a function of the form $y = f(x \pm vt)$. In options $A$,$B$,and $C$,the arguments are of the form $(x - vt)$,$(x + vt)$,and $(x - vt)$ respectively,which satisfy the condition for a travelling wave. In option $D$,the argument is $(x^2 - vt^2)$. This does not represent a travelling wave because it cannot be expressed as a function of $(x \pm vt)$. Therefore,$y = f(x^2 - vt^2)$ does not represent a travelling wave.
