Answer:
Explanation:
The answers you put are correct...
crest- A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum.
wavelength- In physics, the wavelength is the spatial period of a periodic wave the distance over which the wave's shape repeats. (how long the wave is)
trough- A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
amplitude- Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
Hope this helps! Have a great day!! :D
