With the sound waves in phase at 688 hz and the speed of sound in air to be 344 m/s we have a wavelength of 0.5 m
To solve this problem the formula and the procedure that we have to use is:
λ = v / f
Where:
- f= frequency
- v= wave speed
- λ= wavelength
Information about the problem:
- f= 688 Hz
- v= 344 m/s
- λ = ?
- 1 Hz = s˄ -1
Using the wavelength formula and replacing values we get:
λ = v / f
λ = 344 m/s / 688 Hz
λ =0.5 m
What is frequency?
It is the quantity that measures the number of times or cycles in which a wave is repeated over time in seconds. Frequency is expressed in Hertz (Hz).
