Question

The distance between a compression and the next rarefaction will be:
$\lambda :$ Wavelength

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

Answer 1

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

The distance between two consecutive compressions or rarefactions is called wavelength. It is denoted by symbol $\lambda$. Thus, the distance between a compression and the next rarefaction will be $\frac{\lambda }{2}$.
