In science Trough (geology), a long depression less steep than a trench. Trough (meteorology), an elongated region of low atmospheric pressure. Trough (physics), the lowest point on a wave.

What is a wave trough in physics?
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 is called trough?
Definition of trough 1a : a long shallow often V-shaped receptacle for the drinking water or feed of domestic animals. b : any of various domestic or industrial containers. 2a : a conduit, drain, or channel for water especially : a gutter along the eaves of a building.
What is an example of trough wave?
What is crest and trough in physics?
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.
Is amplitude peak to trough?
Sometimes the difference between values at peak and trough is referred to as an “amplitude”. Context: The distance from peak-to-trough in the business cycle.
What is a peak and trough?
Peak and trough levels indicate drug levels in an individual’s body. A peak is the highest level of a medication in the blood, while a trough level indicates the lowest concentration. Troughs of medication concentration occur after the drug has been broken down and metabolized by the body.
What does a trough do?
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 trough of a wave quizlet?
A trough is the opposite of a crest, so the minimum or lowest point in a cycle. the number of crests of a wave that move past a given point in a given unit of time. The most common unit of frequency is the hertz (Hz), corresponding to one crest per second.
How is a trough formed?
Formation. A trough is the result of the movements of the air in the atmosphere. In regions where there is upward movement near the ground and divergence at altitude, there is a loss of mass. The pressure becomes lower at this point.
What happens during a trough?
A trough in the business cycle is a period of negative gross domestic product (GDP) that forms the lowest point in an economic cycle. It indicates that a recession is underway. A trough in the business cycle is a period of negative gross domestic product (GDP) that forms the lowest point in an economic cycle.
What is a trough in water?
A watering trough (or artificial watering point) is a man-made or natural receptacle intended to provide drinking water to animals, livestock on farms or ranches or wild animals.
What happens when two troughs meet?
When the crests or troughs of two interfering waves meet, their amplitudes add together. This principle is known as constructive interference. So, what happens when the crest of one wave meets the trough of another wave? Well, the opposite happens, and it’s called destructive interference.
What is a negative trough?
Negative tilted troughs usually begin as positive tiled troughs. As the short-wave energy races east though the longwave it distorts its shape from positive to neutral (north-south) orientation to a negative (northwest to southeast) orientation. These types of troughs produce the most severe weather.
Is rarefaction a trough?
The rarefactions are the troughs of the wave.
What is class 11 trough?
Trough: It is the maximum displacement in negative direction. 196 Views. A pipe 20 cm long is closed at one end.
What is trough and crest on a transverse wave?
A transverse is composed of a crest and trough. Crest is the position of maximum upward displacement while trough is the position of maximum downward displacement.
What waves have crests and troughs?
Transverse waves propagate through crests and troughs.
What is difference between peak and trough called?
The structure of a wave The distance from one peak or trough to the next is called wavelength.
What is the peak of a wave called?
The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.
What is called amplitude?
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
What is a trough in a graph?
The opposite of peak in a graph – the lowest part of the line on a graph, between where it falls and rises.
Why are trough levels important?
The trough is the lowest level of the drug while in the therapeutic range. A trough level should be drawn before the next dose is due, and helps determine if the next dose needs to be adjusted, depending on the results. In some cases, the next dose could be skipped or the dose will be decreased for patient safety.
How do you find peak and trough?
A trough level is drawn immediately before the next dose of the drug is administered. A peak level is drawn 1 to several hours after the drug is administered (depending on the drug).
What is a longwave trough?
Longwave Trough A trough in the prevailing westerly flow aloft which is characterized by large length and (usually) long duration.
