Question

The distance between two consecutive compressions and rarefaction is 1.7 m. The wavelength of the wave is.

• A. 2.8 m
• B. 3.4 m
• C. 0.7 m
• D. 4.2 m

Answer 1

Answer: (B)

3.4 m

Wavelength $\lambda$ is defined as the distance between two consecutive compressions or rarefactions, therefore the distance between consecutive compression and rarefaction will be $\lambda /2$,

Given,

$\lambda /2=1.7$

Therefore,

Wavelength of the wave, $\lambda =2\times 1.7=3.4m$
