Question

In a Stationary wave, the distance between a node and the next antinode is 10 cm. What is the value of its wavelength?

Answer 1

Stationary wave with nodes and antinodes is shown in the above figure.

Distance between node and next antinode is $10$ $cm$.

$\therefore$ $\frac{\lambda }{4}=10$ $cm$ where $\lambda$ is wavelength of wave

$⟹$ $\lambda =4\times 10=40$ $cm$
