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 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 the crest and trough of a sound wave?
A crest is the highest point the medium rises to and a trough is the lowest point the medium sinks to.
How do you know if its a trough or crest?

What is crest class 11th?
Hint :In a wave, the maximum value of upward displacement is called its crest. On the other hand trough is just opposite to the crest, in a wave the minimum value of downward displacement is called its trough.
What is 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. the foamy top of a wave.
What is the definition of crest in science?
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 crest and amplitude?
features of waves wave is a called the crest, and the 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.…
What is the top of a wave called?
the crest 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 trough means?
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 a trough 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 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 sound trough?
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 a trough in sound waves?

What is 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 white part of wave called?
White water (or Foam) After the wave breaks, it transforms itself into “whitewater”, also called “foam”.
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 the crest of a transverse wave?
Crest – The highest part of a transverse wave. Trough – The lowest part of a transverse wave. Wavelength – The distance between one crest and the next in a transverse wave. Amplitude – The height from the resting position to the crest of the transverse wave.
What is crest in chemistry?
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.
Why does a wave crest?
As waves reach the shore, the energy in front of the wave slows down due to friction with the shallow bottom. Meanwhile, the energy behind the wave moves at full speed and is channeled upwards, climbing the back of the bulging wave.
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 does crest mean in sound?
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.
What’s the top of a wave called?
the crest 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 are the 3 parts of a wave?
Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest.
What is the tunnel of a wave called?
Barrel: (also tube, cave, keg, green room) The effect when a big wave rolls over, enclosing a temporary horizontal tunnel of air with the surfer inside. Beach break: An area with waves that are good enough to surf break just off a beach, or breaking on a sandbar farther out from the shore.
What is the lip of a wave?
Lip: The lip is when the wave starts to curl over. The larger the wave the more intense and “heavy” the lip can be. Tube: You would have seen many great surfers riding the tube. This is the barrel that has formed one the lip has curled over and is hitting the water creating the impact zone.
What is an example of crest?
The definition of a crest is something that is located at the top of something or someone or a symbol of a family name. An example of crest is the comb on a rooster's head. An example of crest is Mount Lyell in Yosemite. An example of crest is feathers in the top of a medieval helmet.
What is crest in longitudinal wave?
The crest of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position.
