All of them. Electromagnetic, sound, even a water wave until it hits shore.
the wave that has peaks and valleys is a Transverse wave
transverse waves EX. (X-rays)
All waves exhibit both crests and troughs.
They have both.
If you have two waves, or two things in oscillation or two things in vibration; if the peaks (maximum amplitude) and valleys (maximum amplitude the other way) occur at the same time then they are in phase. If one wave peaks at the same time the other one is in a valley they are said to be 180 degrees out of phase.
A halfe-wave rectifier
For a standard 360 deg sine wave with starting point of 0 deg, peaks will occur at 90 deg and 270 deg.
Thread angle is different (55° vs 60°).NPT threads are flattened at the peaks and valleys, while BSPT threads are rounded.Threads per inch (TPI) is different for two (except for a couple of cases).
A; AC. is a sinusoidal wave it has zero potential at some time and speed potential at its peaks. So overall the real effective value to do work is referred by this term. Effective.
Yes. An electromagnetic wave follows a sine-wave pattern.
The wavelength of a transverse wave is the distance between adjacent crests or troughs (peaks or valleys).
Peaks and valleys to not create water waves, they are characteristic elements of water waves.
Sound Waves
They add up.
I'm assuming you mean the sound wave itself. In which case the amplitude increases(the height of the peaks and the depth of the valleys increase).
CHiPs - 1977 Peaks and Valleys 2-1 was released on: USA: 16 September 1978
The first little bump is the P wave it is followed by the QRS Complex that's the big spike and that is followed by the T wave which is a bigger bump than the P wave... normally that's only in a normal Sinus Rhythm
By measuring the distance between the wave peaks!!
the distance between peaks of a wave

It depends which country or region you are talking about.
