Question

question 7 (multiple choice worth 2 points)
(03.03 lc)

which of the following wave properties would be the best way to measure the height of a wave?

amplitude
frequency
equilibrium
trough

Explanation:

Define wave height and amplitude

Using the Wave Anatomy knowledge point

• Wave height is the vertical distance from the trough (lowest point) to the crest (highest point) of a wave.
• Amplitude is the maximum displacement of a wave from its equilibrium (rest) position to either a crest or a trough.
• Therefore, the height of a wave is exactly twice its amplitude (\(\text{Height} = 2 \times \text{Amplitude}\)), making amplitude the best property to measure it.

Evaluate other options

• Frequency: Measures the number of wave cycles passing a point per unit of time, which relates to time rather than vertical height.
• Equilibrium: Represents the rest position of the medium, not a measurement of height.
• Trough: The lowest point of a wave, which is a location rather than a property that measures the overall height.

Answer:

• Amplitude (Correct answer)
• Frequency
• Equilibrium
• Trough
