In a regime of linear propagation (that is almost in any case covered by normal experience) two waves sharing the same space (for example two light waves or two sound waves) generate a third wave (called interference wave) whose amplitude is the sum of the original waves amplitudes and whose phase is the sum of the original waves phases.

If we evaluate the power of the interference wave it is not the sum of the original powers, but it strongly depends on the phases of the original waves.

In particular if the total phase in a point and in an instant is 90° (pi/2) the total power is minimum: it is equal to the difference between the powers of the original waves, that is zero if they had the same power and destructive interference happens.

On the contrary if the sum of the original phases is zero the total power is maximum: twice the sum of the original powers, that is four time the power of one wave if the initial powers were equal and constructive interference is said to happen.

The resultant intensity becomes maximum. In case of light it gives brightest region and in case of sound there is loud sound produced

What occurs when crest overlap crest and troughs overlap troughs?

constructive wave interference, where the crests and troughs 'add' so are increased in amplitude.


The combining of waves as they meet is known as?

Interference. Constructive Interference, which is where the waves increase amplitudes and troughs when they overlap. Destructive Interference, which is where the waves cancel each other out when they overlap.


Why do you not see constructive and destructive interference of white light?

Because there are too many wave lengths to overlap.


What takes place when the crests of one wave overlaps the crest of another wave?

The overlap of one wave crest with another can result in interference, which can be constructive (additional) or destructive (reductive) depending on the phase of the wave.


What is it called when two waves overlap?

When the crest of one wave overlaps the trough of another, this produces destructive interference. If both original waves are equal in amplitude, then nothing will remain. The waves completely cancel out. However, if one waver is larger in amplitude, then there will still be a wave left over after they meet, but it will be smaller. The amplitude of the new wave will be the larger wave amplitude minus the smaller wave amplitude one. The opposite can also occur. If the crests of two waves overlap, then it produces constructive interference (resulting in one larger wave).


What happens when two waves encounter one another in destructive interference?

Destructive interference happens when the crest of one wave and the troughs of another wave overlap. The new wave has a smaller amplitude than the original waves had. When the waves involved in destructive interference have the same amplitude and meet each other at just the right time, the result is no wave at all.


Sometimes waves interfere with one another. What type of interference occurs when the crests of one wave and the troughs of another wave overlap?

destructive interference

Two or more sound waves that overlap?

Sound quality is the term for the bending of overlapping sound wave frequencies through interference.


Why interference not observed in thick film?

Suppose white light is incident from a extended source on a plane parallel thick film viewed in reflected system, then for any value of r, due to large thickness the values of u can be found to satisfy the condition of constructive interference for every colour in the spectrum of white light. The different coloured fringes will overlap to produce general illumination. Thus, a thick film will produce general illumination and no colour will be seen.


What occurs when sound waves overlap and combine?

interference


Does interference occur when one wave is brighter than another and the fainter wave cannot be observed?

Interference does not occur when one wave is brighter than another, and the fainter wave cannot be observed. It occurs when two or more waves overlap.
