Question

letter b in the image represents which part of a wave?
crest
trough
wavelength
amplitude

Explanation:

• Crest: The highest point of a wave. Point C is the crest.
• Trough: The lowest point of a wave. Point A is the trough.
• Wavelength: The distance between two consecutive identical points (e.g., crest - crest or trough - trough). The distance labeled D is the wavelength.
• Amplitude: The maximum displacement from the rest position (equilibrium). The vertical distance labeled B is the amplitude.

Answer:

Amplitude
