Question

a periodic wave is traveling to the right. a snapshot of the wave is pictured below, along with some numbered measurements. complete the statements. the waves amplitude is represented by measurement. the waves wavelength is represented by measurement.

Explanation:

Step1: Recall wave - amplitude definition

The amplitude of a wave is the maximum displacement from the equilibrium position. In the given wave diagram, measurement 3 represents this maximum displacement from the mid - line of the wave.

Step2: Recall wave - wavelength definition

The wavelength of a wave is the distance between two consecutive points that are in phase (e.g., two consecutive crests or troughs). Measurement 1 represents the distance between two consecutive crests, so it is the wavelength.

Answer:

The wave's amplitude is represented by measurement 3.
The wave's wavelength is represented by measurement 1.
