Question

an oscilloscope can be used to produce visible pictures of sound waves. if an oscilloscope is used to measure the distance between the crests of a sound wave, what property of the wave will it be measuring?
○a. wavelength
○b. frequency
○c. amplitude
○d. loudness

Explanation:

• Wavelength: It is defined as the distance between two consecutive crests (or troughs) of a wave.
• Frequency: It is the number of complete waves that pass a given point in a certain time.
• Amplitude: It is the maximum displacement of a wave from its rest position.
• Loudness: It is a subjective perception related to the intensity of the sound wave, not a direct physical property measured by distance between crests.

Answer:

A. wavelength
