Final answer:
The wavelength of a 20 Hz sound made by an elephant, with a sound speed of 344 m/s, is 17.2 meters.
Step-by-step explanation:
the wavelength of this sound can be found:
An elephant makes a call at 20 Hz, and the wavelength of this sound can be found using the speed of sound and the frequency of the call. Given the speed of sound as 344 m/s (which is a typical value for air at room temperature), the wavelength (λ) of the sound can be calculated using the formula: λ = speed / frequency. Let's plug in the values: λ = 344 m/s / 20 Hz = 17.2 meters.
Therefore, the wavelength of the sound produced by the elephant is 17.2 meters. To calculate the wavelength of a sound wave, you can use the formula: Wavelength = Speed of sound / Frequency In this case, the speed of sound in air is given as 344 m/s and the frequency is 20 Hz. Substituting these values into the formula, we get: Wavelength = 344 m/s / 20 Hz = 17.2 m
