What is the result of two waves over laping?

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).


What are four exsamples of constructive forces?

1) Crest of one wave meets the crest of other wave OR Trough of one wave meets the trough of other wave.


Constructive interference occurs when the crest of one wave meets up with the trough of a second wave true or false?

false


True or false destructive interference occurs when a through meets with another trough at a given location on the medium?

True


If the trough of one wave meets the crest of the other?

The amplitudes cancel each other out so the medium is at its base level, however the two waves are still in existence and will continue on their courses despite the apparent annihilation.


What happens to the amplitude of two waves as they meet?

Depends where. If a peak meets a peak, then the amplitude of that peak will increase. Same with troughs. However if the waves have the same amplitude, and a peak meets a trough, they will cancel out, and you will be left with a dead spot, not affected by the wave.


What happens when two sound waves combine if the crest of one wave meets the crest of the other?

for apex learners it is the sound becomes softer or disappears

Wave A has an amplitude of 3 and wave B has an amplitude of 3 What will happen when the trough of wave A meets the trough of wave B?

Constructive interference which theoretically would result in a 6 amplitude as long as the frequency and wavelength of the 2 waves are the same.
