Sep 21, 2019 · Wavelength is the distance between waves. For sound waves, wavelength refers to one complete cycle of rarefaction. The shorter the wavelength, the higher the frequency of the sound. Frequency is measured in Hertz (Hz). One Hertz corresponds to one cycle—in this case, one sound wave—per second. Frequency determines the pitch of a sound. High ...
Sep 12, 2019 · We say sound is a wave because the air molecules move back and forth while the sound travels along. The air behaves much like a longitudinal or compression wave on a spring. It is difficult to draw compression waves , so waves are generally represented as transverse waves for simplicity.
Jul 23, 2023 · Measuring waves. All sound waves are the same: they travel through a medium by making atoms or molecules shake back and forth. But all sound waves are different too. There are loud sounds and quiet sounds, high-pitched squeaks and low-pitched rumbles, and even two instruments playing exactly the same musical note will produce sound waves that are quite different.
Nov 8, 2023 · Condensation is a region in a sound wave in which the sound medium is denser than normal. Decibel (dB) is the unit used to measure the intensity of a sound. A 3,000-hertz tone of 0 dB is the softest sound that a normal human ear can hear. Frequency of a sound is the number of sound waves that pass a given point each second.
In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects (Figure \(\PageIndex{2}\)). Figure \(\PageIndex{1}\): This glass has been shattered by a high-intensity sound wave of the same frequency as the resonant frequency of the glass.
It is too high pitched for humans to hear, but other animals (such as dogs, cats, dolphins and bats) can hear ultrasound. Ultrasound waves are longitudinal waves just like sound waves, and they ...
