Wavelent
One high one low
In a wave, it is called the wave length.
The amplitude is the distance between the the zero position and the crest or the zero position and the trough so the vertical distance means double the amplitude.
No, the distance from one wave crest to the next is notcalled a trough. That distance is called a wavelength. A trough is the lowest point of a wave.
Distance between a trough and crest in a wave is half wavelength
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
wavelength
The vertical distance between the peak and trough is 2*Amplitude.
The distance between the crest and trough of a wave is the peak-to-peak amplitude of the wave.
"wavelength"
You need a tape measure for that!
Waveheight is the vertical distance between crest and trough.
