Question

1. what part of he wave is labeled with an a. wavelength amplitude trough crest

Explanation:

To determine the part of the wave labeled A, we analyze the definitions:

• Wavelength: The distance between two consecutive crests (or troughs) of a wave. In the diagram, A spans from one crest to the next, matching this definition.
• Amplitude: The height of the wave from the midline to a crest (or trough) – this is a vertical measurement, not horizontal.
• Trough: The lowest point of a wave – A is a horizontal distance, not a point.
• Crest: The highest point of a wave – A is a distance, not a point.

Answer:

A. Wavelength
