Quick Answer: What Is Trough In Science?

What does trough mean in science?

Trough (physics), the lowest point on a wave.

What is an example of trough?

The definition of a trough is a long and narrow container. An example of a trough is what pigs eat out of. An example of a trough is a long container in which plants grow next to each other.

Where is the trough in a wave?

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.

What does the trough of a wave look like?

Waves have moving crests (or peaks) and troughs. A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to. Crests and troughs on a transverse wave are shown in Figure 8.2. A point on the wave is a trough if the displacement of the medium at that point is at a minimum.

Whats does trough mean?

Why is it called a trough?

Being unusually cold makes it unstable, which then makes air in that part of the atmosphere want to rise. These low-pressure situations are called troughs. The word trough — as in, horse trough — is just a metaphor used to describe a line of low pressure stretching from one place to another.

What happens during trough?

A trough is the stage of the economy’s business cycle that marks the end of a period of declining business activity and the transition to expansion. These increase during expansion, recede during contraction, and bottom out during a trough.

What is definition of feeding trough?

noun A trough in which is placed food for animals, especially for swine. noun A long, narrow trough, about 18 inches wide, 4inches deep, and 1,500 feet long, placed between the rails of a railway-track and partly filled with water.

What is the use of trough?

What is a trough on a graph?

The opposite of peak in a graph – the lowest part of the line on a graph, between where it falls and rises.

What is the frequency of the wave?

The frequency, represented by the Greek letter nu (ν), is the number of waves that pass a certain point in a specified amount of time. Typically, frequency is measured in units of cycles per second or waves per second. One wave per second is also called a Hertz (Hz) and in SI units is a reciprocal second (s1).

What are the parts of the wave?


  • crest. Noun. the top of a wave.
  • wave. Noun. moving swell on the surface of water.
  • wave height. Noun. the distance between a wave’s trough and crest.
  • wavelength. Noun. the distance between the crests of two waves.
  • wave trough. Noun. the lowest part of a wave.

What is a trough weather?

A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure. Air in a high pressure area compresses and warms as it descends. This warming inhibits the formation of clouds, meaning the sky is normally sunny in high-pressure areas.

What is the meaning of crest and trough?

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.
