Question

the amplitude of a transverse wave is the largest displacement of a part of the medium. in other words, amplitude is the distance between the equilibrium position and a crest, or between the equilibrium position and a trough. the wavelength of a transverse wave is the length of one complete wave cycle. in other words, the wavelength is the distance from crest to crest, or from trough to trough. this model shows the transverse wave in a battle rope. label the model. crest equilibrium position wavelength trough amplitude

Explanation:

• Crest: The highest point of the wave.
• Equilibrium position: The position of the medium when no wave is passing through (the dotted line).
• Wavelength: The distance between two consecutive crests (or troughs).
• Trough: The lowest point of the wave.
• Amplitude: The distance from the equilibrium position to a crest (or trough).

Answer:

Label the highest point of the wave as "crest", the dotted line as "equilibrium position", the distance between two consecutive crests (or troughs) as "wavelength", the lowest point of the wave as "trough", and the distance from the equilibrium position to a crest (or trough) as "amplitude".
