Question

1. define a property of a sound wave.

Explanation:

One property of a sound wave is frequency. Frequency refers to the number of oscillations (vibrations) a sound wave completes per unit time, measured in hertz (Hz). It determines the pitch of the sound—higher frequency means higher pitch (e.g., a whistle has a higher frequency than a bass drum), and lower frequency means lower pitch. Another common property is amplitude, which is the maximum displacement of particles in the medium from their rest position as the wave passes; it relates to the loudness (intensity) of the sound, with greater amplitude corresponding to louder sound. Wavelength is also a property, defined as the distance between two consecutive corresponding points (like two crests or two troughs) on the wave, and it's related to frequency and the speed of sound in the medium by the formula \( v = f\lambda \) (where \( v \) is speed, \( f \) is frequency, and \( \lambda \) is wavelength). For this answer, we'll focus on frequency as a key property.

Answer:

A property of a sound wave, e.g., Frequency: The number of oscillations (vibrations) a sound wave makes per unit time (measured in hertz, Hz), determining the pitch (higher frequency = higher pitch, lower frequency = lower pitch).
