Question

what does the wavelength of a wave measure?
the number of waves that pass a point per second.
the distance between two consecutive peaks of a wave.
the speed at which the wave is traveling.
the maximum height of a wave from its resting position.

Explanation:

Wavelength is a fundamental property of waves, defined as the spatial distance between identical consecutive points on a wave, such as two peaks (crests) or two troughs. The other options describe different wave properties: the number of waves per second is frequency, wave speed is the rate of wave propagation, and maximum height from rest is amplitude.

Answer:

B. The distance between two consecutive peaks of a wave.
