label the parts of a wave the terms : crest ,trough, frequency, wavelength, amplitude
The Correct Answer and Explanation is:
Here is the correct labeling of the parts of a wave using the terms provided:
1. Crest
The highest point of the wave. It is the peak or topmost part above the rest position of the wave.
2. Trough
The lowest point of the wave. It is the bottommost part below the rest position of the wave.
3. Wavelength
The distance between two consecutive crests or two consecutive troughs. It measures the length of one complete wave cycle.
4. Amplitude
The distance from the rest position (equilibrium line) to the crest or from the rest position to the trough. It represents the height or strength of the wave.
5. Frequency
The number of complete wave cycles that pass a given point in one second. Frequency is measured in hertz (Hz).
Explanation:
Waves are repeating disturbances or vibrations that transfer energy from one place to another. Whether in water, sound, or light, waves share common properties that help describe their behavior and characteristics.
The crest is the peak of the wave, representing the maximum upward displacement from the wave’s rest position. Conversely, the trough is the lowest part of the wave, representing the maximum downward displacement. Together, crests and troughs illustrate the oscillating motion of a wave.
The wavelength is the spatial length of one full wave cycle. It is commonly measured from crest to crest or from trough to trough. Wavelength is crucial for determining how stretched or compressed the wave appears.
The amplitude is the measure of the wave’s energy. It is the vertical distance from the rest position to the crest or from the rest position to the trough. Waves with greater amplitude carry more energy, while waves with smaller amplitude carry less energy.
Frequency describes how often a wave repeats in a given time frame, usually one second. It tells us how many complete cycles pass a specific point per second. High-frequency waves have more cycles occurring quickly, while low-frequency waves have fewer cycles in the same time period.
Understanding these parts of a wave helps in analyzing wave behavior in different areas such as sound, light, and water movement.
