What is a wave that has all the crests and troughs in the same place at the same time?

Waves traveling in opposite directions can produce standing waves. A standing wave is a wave that has crests and troughs at fixed points; the amplitude changes in time, but the locations of crests do not. The figure below shows a standing wave at three different times.

What does the trough of a wave refer to?

The trough of a wave is the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position. The wave shown above can be described by a variety of properties. One such property is amplitude.

What is the physical meaning of the wave function of an electron?

probability amplitude
The physical meaning of the wave function is an important interpretative problem of quantum mechanics. The standard assumption is that the wave function of an electron is a probability amplitude, and its modulus square gives the probability density of finding the electron in a certain location at a given instant.

What do you mean by crest and trough?

The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.

What is a crest in geography?

noun. the highest part of a hill or mountain range; summit. the head or top of anything. a ridge or ridgelike formation.

Is electron a wave or particle?

Along with all other quantum objects, an electron is partly a wave and partly a particle. To be more accurate, an electron is neither literally a traditional wave nor a traditional particle, but is instead a quantized fluctuating probability wavefunction.

What is a trough in physics?

Trough – the lowest point below the rest position. Amplitude – the maximum displacement of a point of a wave from its rest position. Wavelength – distance covered by a full cycle of the wave. Usually measured from peak to peak, or trough to trough.

What is crest and trough in physics?

From Wikipedia, the free encyclopedia. A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
