Question

The distance between two consecutive compressions is $1.4m$. The wavelength of the wave is

• A. $2.8m$
• B. $1.4m$
• C. $0.7m$
• D. $4.2m$

Answer 1

Answer: (B)

$1.4m$

Wave length $\lambda$ is defined as the distance between two successive compressions or rarefactions .

It is given that the distance between two successive compressions is 1.4m, therefore wavelength $\lambda =1.4m$ .
