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)
Which of the following is the best option?
a) 17 m
b) 6,800 m
c) 0.059 m
d) 170 m
c) 0.059 m.
To find the wavelength, we use the formula:
wavelength = speed of sound / frequency
Substituting the given values, we get:
wavelength = 340 m/s / 20 Hz = 17 m/s
Therefore, the wavelength of the low sound is 0.059 m.
To calculate 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 about 20 Hz 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
Dividing 340 m/s by 20 Hz gives us:
wavelength = 17 m
Therefore, the correct option is:
a) 17 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 about 20 Hz and the speed of sound in air is 340 meters/second, we can plug these values into the formula to calculate the wavelength:
wavelength = 340 m/s / 20 Hz
wavelength = 17 meters
Therefore, the correct answer is:
a) 17 m
