The lowest frequency that we can hear is about 20 hertz. If the speed of sound in air is 340 meters/second, what is the wavelength of that low sound?(1 point)
Responses
A. 170 m
B. 6,800 m
C. 0.059 m
D. 17 m
C. 0.059 m
To find the wavelength of a sound wave, we can use the formula:
Wavelength = Speed of Sound / Frequency
Given that the lowest frequency we can hear is 20 hertz and the speed of sound in air is 340 meters/second, we can substitute these values into the formula:
Wavelength = 340 m/s / 20 Hz
Calculating this, we get:
Wavelength = 17 m
Therefore, the correct answer is option D. 17 m.
To find the wavelength of a sound wave, we can use the formula:
Wavelength = Speed of Sound / Frequency
In this case, the lowest frequency we can hear is given as 20 hertz, and the speed of sound in air is 340 meters/second. Let's plug these values into the formula:
Wavelength = 340 meters/second / 20 hertz
Simplifying this:
Wavelength = 17 meters
Therefore, the correct answer is D. 17 m
