What does the trough of a wave represent?

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.

Do light waves have crests and troughs?

Waves and the Spectrum of Light Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength.

What is the crest of a light wave?

The crest is the highest point of the wave and the trough is the lowest point of the wave.

What type of waves are crests and troughs?

The high point of a transverse 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.

What is trough and crest on a transverse wave?

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 crest is a point on the wave where the displacement of the medium is at a maximum.

How does crest and trough are produced in a water wave?

8.3 Crests and troughs (ESACM) 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.

What is trough science?

Trough – the lowest point below the rest position. Amplitude – the maximum displacement of a point of a wave from its rest position. Wavelength – distance covered by a full cycle of the wave. Usually measured from peak to peak, or trough to trough.

What is trough and crest of a transverse wave?

What is a crest in a transverse wave?

Transverse waves are those in which the wave components (i.e. the individual parts of the medium that is transferring the wave) oscillate in a perpendicular direction to that of the wave motion. The crest of a wave is the highest point that it reaches, while the trough of the wave is the lowest point.

What does the word crests mean?

a : peak especially : the top line of a mountain or hill. b : the ridge of a roof. c : the top of a wave.

What is trough in geography?

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. The weather charts in some countries or regions mark troughs by a line.
