What is meant by 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.
What is a 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 is a trough called?
chute, slide, slideway, sloping trough. sloping channel through which things can descend. cullis. a gutter in a roof. coal chute.
What is trough in physics class 9?
When a transverse wave travels the upper portion (displacement) of wave is called crest and lower portion is called trough as shown in diagram below-
What does trough mean example?
1. 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. noun.
What is trough in 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 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.
What is a trough used for?
a long, narrow, open receptacle, usually boxlike in shape, used chiefly to hold water or food for animals.
What is trough and ridge?
Ridges and troughs are often mentioned on the weather forecast. A ridge is an elongated area of relatively high pressure extending from the center of a high-pressure region. A trough is an elongated area of relatively low pressure extending from the center of a region of low pressure.
What are peaks and troughs?
Peaks and troughs are the highest and lowest concentrations, respectively, of a medication in an individual's body. They are used to determine dosing intervals, especially during therapeutic drug monitoring.
What is crest and trough in 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 is compression and rarefaction?
Compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart. The region where the medium is compressed is known as compression and the region where the medium is spread out is known as a rarefaction.
Is trough a low point?
trough noun (C) (LOW POINT) (in the study of weather patterns) a long area of low air pressure between two areas of high air pressure: A trough of low pressure over hilly areas will bring heavy thunderstorms overnight.
What is the trough of a longitudinal wave?
low point is called the trough. For longitudinal waves, the compressions and rarefactions are analogous to the crests and troughs of transverse waves. The distance between successive crests or troughs is called the wavelength. The height of a wave is the amplitude.
Why is low pressure called a trough?
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map.
What are peak and trough levels?
The trough level is the lowest concentration in the patient's bloodstream, therefore, the specimen should be collected just prior to administration of the drug. The peak level is the highest concentration of a drug in the patient's bloodstream.

What is a peak level?
Peak level is the instantaneous measurement of level. It's important because it lets us know the highest level of the audio and how close it is to the ceiling, or the maximum allowable level before distortion. Average level is a measurement of the average energy that occurs over a window of time.
What is crest or trough of light?
The crest is the highest point of the wave and the trough is the lowest point of the wave.
What is contraction and rarefaction?
Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.
What is a rarefaction in physics?
Rarefaction is the reduction of an item's density, the opposite of compression. Like compression, which can travel in waves (sound waves, for instance), rarefaction waves also exist in nature. A common rarefaction wave is the area of low relative pressure following a shock wave (see picture).
What is ridge and trough?
A ridge is an elongated area of relatively high pressure extending from the center of a high-pressure region. 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.
What is crests and troughs in transverse waves?
Crests and troughs on a transverse wave are shown in Figure 8.2. Figure 8.2: Crests and troughs in a transverse wave. A crest is a point on the wave where the displacement of the medium is at a maximum. A point on the wave is a trough if the displacement of the medium at that point is at a minimum.
Is trough transverse or longitudinal?
While a transverse wave has an alternating pattern of crests and troughs, a longitudinal wave has an alternating pattern of compressions and rarefactions. As discussed above, the wavelength of a wave is the length of one complete cycle of a wave.

What is a trough measurement?
The trough level is the lowest concentration in the patient's bloodstream, therefore, the specimen should be collected just prior to administration of the drug. The peak level is the highest concentration of a drug in the patient's bloodstream.
Why do we measure peak and trough?
Peak and trough levels are drawn to determine a drug's concentration within the system. They help determine if a drug is in a toxic range or if the dosage of the medication needs to be increased. It is important to know which medications need to be monitored and what the signs and symptoms of toxicity are.
How does a trough move?
Troughs and ridges are related to jet streams. A trough is a southward or downward dip in the wind current, while a ridge is a northward or upward hump in the jet stream. In the Northern hemisphere, the wind around a trough blows counterclockwise but clockwise around a ridge.
What is the 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 is RMS and peak?
The peak value is the highest voltage that the waveform will ever reach, like the peak is the highest point on a mountain. The RMS (Root-Mean-Square) value is the effective value of the total waveform. It is equal to the level of the DC signal that would provide the same average power as the periodic signal.
