letter b in the image represents which part of a wave?\ncrest\ntrough\nwavelength\namplitude

Brief Explanations:

• Crest: The highest point of a wave. In the image, point C is the crest.
• Trough: The lowest point of a wave. In the image, point A is the trough.
• Wavelength: The distance between two consecutive crests or troughs. In the image, segment D represents the wavelength.
• Amplitude: The maximum displacement from the rest position (the mid - line of the wave). In the image, segment B represents the amplitude as it measures the height from the rest position to the crest (or depth from the rest position to the trough).

Answer:

Amplitude
