Question

What is the wavelength if the distance between a crest and immediate trough in a transverse wave is 15 m?

• A. 30 m
• B. 40 m
• C. 50 m
• D. 15 m

Answer 1

The correct option is A 30 m

The distance between two successive crests or troughs is the wavelength $\left(\lambda \right)$.

Thus, the distance between between a crest and immediate trough $=\lambda /2$

or $15=\lambda /2$

or $\lambda =30m$
