How would you describe the amplitude of a wave?
The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next. The amplitude or height of a wave is measured from the peak to the trough.
How would you describe the crest and the trough of 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. The horizontal distance between two adjacent crests or troughs is known as the wavelength.
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.
Which definition describes the amplitude of a wave quizlet?
What is Amplitude? The maximum distance the medium vibrates from the rest position.
Which describes the amplitude of a wave when it carries more energy?
The amount of energy carried by a wave is related to the amplitude of the wave. A high energy wave is characterized by a high amplitude; a low energy wave is characterized by a low amplitude.
What is the amplitude of a transverse wave?
In a transverse wave, amplitude is the measure from the resting position to either the crest (high point of the wave) or to the trough (low point of the wave.)
How do scientists use the terms wavelength crest and trough?
Scientists Say: Wavelength Scientists use several properties to measure and describe all these types of waves. Wavelength is the distance from one point on a wave to an identical point on the next, such as from crest to crest or from trough to trough. Waves can come in a wide range of lengths.
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 point on the wave is a trough if the displacement of the medium at that point is at a minimum.
How are waves measured from crest to crest?
In order to measure waves, you look at the distance between a point on one wave to that exact same point on the next wave. Let’s say from crest to crest. The length between the same point on two waves is called the wavelength. This is an easy one to remember.
What’s the highest point on a wave called?
Finally, you reach the top. You can rest for a second. This highest point on the wave is called the crest. From here, you will be able to see the dips in front of and behind you as well as the crests of those hills. What’s a good way to remember crest?
How is the amplitude of a wave measured?
The amplitude is shown on the graph below. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave.
How are the properties of a wave calculated?
Properties of Waves. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the amplitude will measure the loudness of the sound.
