Question: 1 / 400

What does amplitude refer to in a wave?

The distance between two peaks

The height of the wave from the midpoint to the peak

Amplitude refers to the maximum extent of a vibration or oscillation, measured from the position of equilibrium or the midpoint of the wave to its peak (or trough) in the context of waves. It represents the strength or intensity of the wave, with higher amplitude indicating a greater energy level for various types of waves, including sound and electromagnetic waves.

In this case, the measurement from the midpoint to the peak accurately describes the amplitude, as it captures the maximum displacement of the wave's oscillation from its average value. Understanding amplitude is crucial for interpreting wave behavior, as it directly influences how we perceive traits like loudness in sound waves or brightness in light waves.
