Question

The distance between a compression and the adjacent rarefaction is

• A. $\frac{\lambda }{2}$
• B. $\lambda$
• C. $\frac{\lambda }{4}$
• D. $\frac{\lambda }{3}$

Answer 1

The correct option is A $\frac{\lambda }{2}$

The distance between two successive compressions or rarefactions, is equal to wavelength $\left(\lambda \right)$ of the wave. Hence, the distance between a compression and the adjacent rarefaction would be $\frac{\lambda }{2}$.
