One dimensional wave equation is
1
\(\frac{{{\partial ^2}y}}{{\partial {t^2}}} = {\alpha ^2}\frac{{{\partial ^2}y}}{{\partial {x^2}}}\)
2
\(\frac{{\partial y}}{{\partial t}} = {\alpha ^2}\frac{{{\partial ^2}y}}{{\partial {x^2}}}\)
3
\(\frac{{{\partial ^2}y}}{{\partial {t^2}}} = -\frac{{{\partial ^2}y}}{{\partial {x^2}}}\)
4
None of these
