The wave pattern on a stretched string is shown in figure. Interpret what kind of wave this is and find its wavelength.
The wave pattern on a stretched string is shown in figure. Interpret what kind of wave this is and find its wavelength.
Here, particles at $x=10,20,30,40, \ldots \mathrm{cm}$ remain stationary at their respective mid points of path of oscillation, which is a characteristic of nodal points. Distance between two consecutive nodal points is $\frac{\lambda}{2}$ which is here,
$\frac{\lambda}{2}=(20-10)=10$
$\therefore \lambda=20 \mathrm{~cm}$
