The distance between two consecutive crests or troughs is called:
Correct answer: B. Wavelength
- A. Amplitude
- B. Wavelength
- C. Time period
- D. Frequency
Explanation
Wavelength (λ) is the distance between two points on a wave that are in the same phase - e.g. two crests or two troughs. It tells how "long" one wave is.

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.
