What are troughs in physics?
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.
What is the best definition of trough?

What is a trough called?

What are troughs in rivers?
a channel or conduit for conveying water, as a gutter under the eaves of a building for carrying away rainwater.
What is 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 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 a trough in chemistry?
noun. chemistry. a shallow dishlike vessel filled with a liquid, usually water, and used in collecting gases by displacement of liquid from a filled jar held with its open end under the surface of the liquid.
What is a trough in waves?
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 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 is ocean trough?
oceanic trough, an elongate depression in the seafloor that is characteristically shallower, shorter, narrower, and topographically gentler than oceanic trenches. Maximal depths of oceanic troughs range between 2,300 m (7,500 feet) in the Papuan Trough and 7,440 m in the Banda Trough.
What is a trough in the ocean?
oceanic trough, an elongate depression in the seafloor that is characteristically shallower, shorter, narrower, and topographically gentler than oceanic trenches.
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 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 mercury trough?
noun In chem., a trough (generally of porcelain, cast-iron, or wood) used to hold mercury over which, in glass jars or tubes, gases are collected which, on account of their solubility, can not well be collected over water: essentially, a pneumatic trough containing mercury instead of water.
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.
What is the trough of a mountain?
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 is trench basin?
Regions of deeper water are referred to as basins, trenches or troughs (indicated in blue). Basins and troughs are large areas of relatively uniform depth, much like plains on land, while trenches have much steeper sides, more like river gorges.
What is a trench in geology?
Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth. 5 – 12+ Earth Science, Geography, Geology, Physical Geography. Photograph.
What is the meaning of trough in chemistry?
noun. chem a shallow dishlike vessel filled with a liquid, usually water, and used in collecting gases by displacement of liquid from a filled jar held with its open end under the surface of the liquid.
What is called crest?
As a verb, crest means "to reach the top" like when you crest a mountain. Definitions of crest. the top or extreme point of something (usually a mountain or hill) synonyms: crown, peak, summit, tip, top. types: brow, hilltop.
What is trough chemistry?
noun. chemistry. a shallow dishlike vessel filled with a liquid, usually water, and used in collecting gases by displacement of liquid from a filled jar held with its open end under the surface of the liquid.
What is the use of a trough in chemistry?
A pneumatic trough is a piece of laboratory apparatus used for collecting gases, such as hydrogen, oxygen and nitrogen.
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 the difference between trench and trough?
Basins and troughs are large areas of relatively uniform depth, much like plains on land, while trenches have much steeper sides, more like river gorges. The deepest waters occur in trenches, which also mark the boundaries of continental plates.
What is the deep ocean called?
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Where is a trench formed?
At least one of the plates is oceanic lithosphere, which plunges under the other plate to be recycled in the Earth's mantle. Trenches are related to but distinguished from continental collision zones (such as that between India and Asia forming the Himalaya), where continental crust enters a subduction zone.
What is the bottom of a wave called?
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 laboratory trough?
A pneumatic trough is a piece of laboratory apparatus used for collecting gases, such as hydrogen, oxygen and nitrogen.
What is water trough in laboratory?
Water trough used for containing water when collecting gases. Retort stand used for hanging apparatus. and supporting apparatus during experiments.
What is trough ocean?
oceanic trough, an elongate depression in the seafloor that is characteristically shallower, shorter, narrower, and topographically gentler than oceanic trenches.
