Distance between any two consecutive crests or troughs is called:
Correct answer: C. Wavelength
- A. Frequency
- B. Period
- C. Wavelength
- D. Phase difference
Explanation
The correct answer is wavelength because it specifically refers to the spatial distance between two consecutive crests or troughs in a wave. This is a key feature of wave properties, distinguishing it from other concepts such as frequency, which deals with how often waves pass a point in time, and period, which is the time for one complete wave cycle. Phase difference, on the other hand, pertains to the angular shift between two waveforms, not a physical distance.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
