For the transverse wave equation, $y=A \sin (\pi x+\pi t)$, choose the correct option at t=0.
A transverse sinusoidal wave of amplitude $a$, wavelength $\lambda$ and frequency $n$ is travelling on a stretched string. The maximum speed of the particle is $\frac{1}{10} t h$ of the speed of propagation of the wave. If $a=10^{-3} \mathrm{~m}$ and $V=10 \mathrm{~m} / \mathrm{s}$, then $\lambda$ are given by -
The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation.
$$
y(t)=A \sin (\omega t+\phi)
$$
Here $\omega$, is the angular frequency i.e,
$$
\omega=\frac{2 \pi}{T}=2 \pi f_{\text {It defines how many cycles of the oscillations are there. }}
$$
and $\phi=$ phase angle
General form:
a spatial variable x that represents the position on the dimension on which the wave propagates, and a characteristic parameter k called wave number which represents the proportionality between the angular frequency ω and the linear speed (speed of propagation ) ν. which is
$y(x, t)=A \sin (k x-\omega t+\phi)$ when the wave is moving towards the right
$y(x, t)=A \sin (k x+\omega t+\phi)$ when the wave is moving towards the left.
The wavenumber is related to the angular frequency by:
$$
k=\frac{\omega}{v}=\frac{2 \pi f}{v}=\frac{2 \pi}{\lambda}
$$
Also,
$$
\begin{aligned}
& \text { Particle velocity }=-(\text { wave velocity }) \times(\text { slope of } y \text { vs } \times \text { graph }) \\
& \Longrightarrow V_p=-v\left(\frac{\partial y}{\partial x}\right) \\
& \Longrightarrow \frac{\partial y}{\partial t}=-v\left(\frac{\partial y}{\partial x}\right)
\end{aligned}
