Want this question answered?
Yes. An electromagnetic wave follows a sine-wave pattern.
All of them. Electromagnetic, sound, even a water wave until it hits shore.
The wavelength of a transverse wave is the distance between adjacent crests or troughs (peaks or valleys).
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).
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
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.
The distance between two adjacent wave peaks (or troughs).
Measure the height of its peaks
wavelength
