The distance between any two consecutive crests or troughs is called____________________?
Correct answer: C. Wave length
- A. frequency
- B. period
- C. Wave length
- D. phase difference
Explanation
The distance between two successive crests or two successive troughs is one wavelength, λ. These points are in the same phase and the separation is one complete spatial cycle. The likely mistake is choosing period, which is the time for one complete oscillation, not a distance.

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.
