A travelling transverse wave has amplitude a and wavelength λ. What is the minimum distance between a crest and a trough in the direction of propagation of wave?
Correct answer: D. λ/2
- A. 2a
- B. a/2
- C. 2λ
- D. λ/2
Explanation
The distance between a crest and a consecutive trough is half of the wavelength. The highest surface part of a wave is called the crest, and the lowest part is the trough

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
