A horizontal stretched string, fixed at two ends, is vibrating in its fifth harmonic according to the equation, $\text{y}\left(\text{x},\text{t}\right)=\left(\text{0.01 m}\right)sin\left[\left({62.8\; m}^{-1}\right)x\right]cos\left[\left({628\; s}^{-1}\right)t\right]$. Assuming $\pi =\text{3.14}$, the correct statement(s) is (are)
