Question

The time taken by a particle in reaching from a trough to its next crest in a transverse wave is

• A. T/4
• B. T/2
• C. T
• D. 3T/4

Answer 1

The correct option is B T/2

A crest and a trough are separated by a distance of $\lambda /2$. A distance of $\lambda /2$ corresponds to a time difference of T/2
