What point on the image provided represents a wavelength?
What point on the image provided represents a wavelength?
A wavelength is the length of a complete wave cycle, from one crest to the next crest or one trough to the next trough.
Point A is the length from one crest to the next crest; thus, point A represents a wavelength.
A wavelength is the length of a complete wave cycle, from one crest to the next crest or one trough to the next trough.
Point A is the length from one crest to the next crest; thus, point A represents a wavelength.

What point on the image provided represents a trough?
What point on the image provided represents a trough?
The trough of a wave is the lowest most point that a wave falls downward. Point B is at the lowest most point of a wave.
The trough of a wave is the lowest most point that a wave falls downward. Point B is at the lowest most point of a wave.

What point on the image provided represents an amplitude?
What point on the image provided represents an amplitude?
The amplitude is the distance from rest to a crest or from rest to a trough. Point D represents the distance from rest to the trough; thus, point D is the correct answer.
The amplitude is the distance from rest to a crest or from rest to a trough. Point D represents the distance from rest to the trough; thus, point D is the correct answer.
