Question

1 on the graphic provided label the following parts of a wave: its wavelength, half of a wavelength, amplitude, a crest, a trough, and a node. a how many wavelengths are represented in the wave above? b what is the amplitude of the wave shown?

Explanation:

a. A wavelength is the distance between two identical adjacent points on a wave (e.g., peak to peak, trough to trough). Counting these segments on the wave diagram gives the total number of wavelengths.
b. Amplitude is the maximum distance a wave oscillates from its equilibrium (central) line, measured from the center to the peak or trough.

Answer:

a. 2 complete wavelengths are represented in the wave diagram.
b. The amplitude of the wave is the distance from the central equilibrium line to either the highest peak or lowest trough of the wave (the specific value would correspond to the marked vertical measurement on the diagram's y-axis).
