Understanding the Relationship
* Speed of Sound: The speed of sound in air at room temperature is approximately 343 meters per second (m/s).
* Wavelength: The wavelength (λ) is the distance between two consecutive crests or troughs of a wave.
* Frequency: The frequency (f) is the number of wave cycles that pass a point per second.
The Formula
The relationship between these three is:
* Speed of Sound (v) = Wavelength (λ) × Frequency (f)
Solving for Frequency
1. Rearrange the formula: f = v / λ
2. Plug in the values: f = 343 m/s / 78 m
3. Calculate: f ≈ 4.40 Hz
Therefore, the frequency of the sound wave is approximately 4.40 Hertz.
Important Note: This frequency is extremely low. Human hearing typically ranges from about 20 Hz to 20,000 Hz. This sound wave would be well below the range of human hearing.
