Question

one complete cycle, or the time it takes a wave to travel a distance equal to its wavelength, is known as a ______. answer options: select one of four period curve velocity frequency

Explanation:

To solve this, we analyze each option:

• "period": Defined as the time for one complete wave cycle (or to travel one wavelength), matching the description.
• "curve": Refers to a graphical shape, not time-related to wave cycles.
• "velocity": Is wave speed (distance/time), not the time for a cycle.
• "frequency": Is cycles per unit time, not the time for one cycle.

Answer:

A. period
