Final answer:
The wavelength of a sound wave traveling at 331 m/s with a frequency of 126 Hz is approximately 2.63 meters.
Step-by-step explanation:
To determine the wavelength of a sound wave, you can use the formula wavelength = velocity / frequency.
Given that the velocity (speed) of the sound wave is 331 m/s and the frequency is 126 Hz, you can substitute these values into the formula:
wavelength = 331 m/s / 126 Hz
wavelength ≈ 2.626984127 m
So, the wavelength of the sound wave is approximately 2.63 meters.
