If a pulse "interferes" with another pulse, they build each other up to form supercrests or supertroughs. This process is known as constructive interference.
Constructive interference occurs, the two waves are said to be "in phase." This results in the amplitudes of the two waves at that point add up, creating a louder or brighter wave for example.
Destructive interference takes place.
Constructive interference occurs when the trough of one wave passes through the crest of another wave
They get canceled out if they have the same magnitude.

Phenomenon of interference.
Resonance.
The crest of a fold is its highest part with the trough being its lowest. Folds result when rock is bent and thus permanently deformed.
In an anticline, the fold is at the top, called the crest. The syncline, in contrast, is the trough of the "wave."
Crest, and the least dense the Trough
You are probably asking how Wavelegth is measured.......yes the distance between similar points on any waves is the WAVELENGTH . You count the number per second to get the FREQUENCY in cycles per second or HERTZ.... If the Frequency is very low it may take more than one second to complete a wave , then the Frequency is a fraction of a Hertz .ie 0.5hz takes two seconds to complete one wave.....

They get canceled out if they have the same magnitude.
Destructive interference occurs when the amplitudes of two waves combine to produce a wave with a smaller amplitude.

This is called "destructive interference" and the waves cancel each other out into what is called a "node" or "nodal point".
Wavelength.
Destructive interference takes place. Constructive interference occurs when the trough of one wave passes through the crest of another wave
Constructive interferences occur when two waves combine (add up) by the superpostition principle. Destructive interferences occur when the crest of one wave interferes with the trough of another. Amplitudes are subtracted.
When the crest, or high point, of one wave passes through the crest of another wave, both of the crests' heights are added into one larger crest. After they pass, each crest becomes its original height that they were before the incident. This phenomena called constructive interference. This also occurs when the trough, or low point, of a wave passes through the trough of another. Now, when the crest of one wave passes through the trough of another, the height and depth of each is added (think of the trough's depth as a negative number) and the resulting amplitude (the distance from the middle of the wave) is "constructed". And once again, after the crest and trough finish passing each other, both crest and trough become their original amplitude that they were before the incident. This phenomena is called destructive interference.
I'm guessing you're talking about Transverse waves? eg. ~ Waves consist of two parts - a crest and a trough. The crest are the high points, and a trough is the low points. When a crest meets another crest, the wave is amplified, causing constructive interference (the crests add to each other). The same thing occurs when a trough meets a trough. However, when a crest meets a trough, the wave is diminished, causing destructive interference (the crest and trough cancel each other out).
