The distance between corresponding points on adjacent waves is called what?

• A. Frequency
• B. Wavelength
• C. Quantum
• D. Molar mass

Answer: (B)

The distance between identical points of adjacent waves is the wavelength. It measures how far a wave travels before its pattern repeats, for example from one crest to the next crest. This spatial period is connected to how fast the wave moves and how often it repeats in time, through the relationship v = f λ. So, if the speed is fixed, a higher frequency means a shorter wavelength, and vice versa. The other terms don’t describe a spatial spacing: frequency is how often the cycle occurs per second, a quantum is a packet of energy, and molar mass is a property of matter unrelated to wave spacing.
