At 0°C sound travels through air at a speed of 330 m/s. If a sound wave is produced with a wavelength of 0.90 m, what is the wave’s frequency?
To find the wave's frequency, we can use the formula:
Speed = Wavelength × Frequency
Given that the speed of sound is 330 m/s and the wavelength is 0.90 m, we can rearrange the formula to solve for frequency:
Frequency = Speed / Wavelength
Substituting the given values into the equation, we get:
Frequency = 330 m/s / 0.90 m
Simplifying the equation, we find:
Frequency = 366.67 Hz
Therefore, the wave's frequency is approximately 366.67 Hz.
To find the wave's frequency, you can use the formula:
frequency = speed / wavelength
where:
- frequency is the number of complete waves that pass a point in a given time (measured in Hertz, Hz),
- speed is the rate at which the wave travels through the medium (in meters per second, m/s), and
- wavelength is the distance between two corresponding points on a wave (in meters, m).
Given that sound travels through air at a speed of 330 m/s and the wavelength is 0.90 m, we can substitute these values into the formula:
frequency = 330 m/s / 0.90 m
Simplifying this equation, we get:
frequency = 366.67 Hz
Therefore, the wave's frequency is approximately 366.67 Hz.
The wave equation is nice.
frequency*wavelength= speed of wave.
solve for frequency.
