Question

The distance between a compression and the next rarefaction will be:

($\lambda$ indicates the wavelength of the wave)

• A. λ/2
• B. λ/4
• C. λ/8
• D. λ/16

Answer 1

The correct option is A

λ/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 $\frac{\lambda }{2}$.
