What is the distance between one wave top to the next wave top called?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Phase

Answer: (A)

Wavelength is the distance from one crest (wave top) to the next crest. It describes the spatial period of the wave and is measured in meters. This spacing links to how fast the wave travels and how often it repeats: lambda = v / f, where speed times frequency yields the distance of one full cycle. The other terms refer to different properties: amplitude is how tall the wave is (its maximum displacement), frequency is how many cycles occur per unit time, and phase is the alignment or offset of the wave within its cycle. So the crest-to-crest distance is the wavelength.
