what is it called when two waves overlap?

Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium.

Rhythmic disturbances that carry energy without carrying matter are called waves. These types of waves, which use matter to transfer energy, are called mechanical waves. the wave energy causes the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels.

Waves that originate from two different, coherent sources produce the property termed as Interference, whereas secondary wavelets that originate from the same wave but occur from different parts of it, produce a phenomenon termed as Diffraction. These both sound alike however they are entirely different by nature.

The phase difference of two waves is the horizontal distance a similar part of one wave leads or lags the other wave. Phase difference is measured in fractions of a wavelength, degrees or radians. In the diagram (above), the phase difference is ¼ λ. This translates to 90o ( ¼ of 360o ) or π/2 ( ¼ of 2π ).

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'.

Categorizing waves on this basis leads to three notable categories: transverse waves, longitudinal waves, and surface waves. A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.

Waves are a disturbance on the surface of the sea or ocean, in the form of a moving ridge or swell.

Longitudinal waves occur when the oscillations are parallel to the direction of propagation. While mechanical waves can be both transverse and longitudinal, all electromagnetic waves are transverse. Sound, for example, is a longitudinal wave.

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium.

The phase difference of two waves is the horizontal distance a similar part of one wave leads or lags the other wave. ... In the diagram (above), the phase difference is ¼ λ. This translates to 90o ( ¼ of 360o ) or π/2 ( ¼ of 2π ).

['The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference.', 'The waves should be monochromatic - they should be of a single wavelength.']

Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves).
607442
The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water.

Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero. ... In the image on the left, the phase difference is δ = π/2 or 90 degrees.

There are the following two conditions for the interference of two light waves: The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference. The waves should be monochromatic - they should be of a single wavelength.

Time period: The time taken by two consecutive compressions or rarefactions to cross a fixed reference point is called the time period (T) of the wave. Amplitude: The magnitude of the maximum disturbance in the medium on either side of the mean value is called the amplitude of the wave.
