The equations of two waves are given by: y_1=5 sin 2 π(x-v t ) cm; y_2=3 sin 2 π(x-v t +1.5) cm These waves are simultaneously passing through a…
The equations of two waves are given by :
$$\begin{aligned}
& y_1=5 \sin 2 \pi(x-v \mathrm{t}) \mathrm{cm} \\
& y_2=3 \sin 2 \pi(x-v \mathrm{t}+1.5) \mathrm{cm}
\end{aligned}
$$
These waves are simultaneously passing through a string. The amplitude of the resulting wave is :
