Question

which of the following refers to the time required for a wave to complete one full cycle?
period
amplitude
wavelength
frequency

Explanation:

To solve this, we analyze each option:

• Period: Defined as the time for a wave to complete one full cycle.
• Amplitude: Maximum displacement of a point on the wave from its rest position (not time - related).
• Wavelength: Distance between two consecutive similar points (e.g., crests) on a wave (distance, not time).
• Frequency: Number of cycles per unit time (not the time for one cycle).

So the correct option is the one labeled "Period".

Answer:

A. Period
