The Relationship
* Velocity (v) = Frequency (f) x Wavelength (λ)
Explanation
* Velocity (v): This is how fast the sound wave travels through the air. It's typically measured in meters per second (m/s).
* Frequency (f): This refers to the number of sound wave cycles that pass a point per second. It's measured in Hertz (Hz). A higher frequency corresponds to a higher pitch.
* Wavelength (λ): This is the distance between two consecutive crests (or troughs) of a sound wave. It's measured in meters (m). A shorter wavelength corresponds to a higher pitch.
Key Points
* Direct Proportionality: The velocity of sound is directly proportional to both frequency and wavelength. This means if you increase either frequency or wavelength, the velocity will also increase.
* Inverse Proportionality: Frequency and wavelength are inversely proportional to each other. If you increase the frequency, the wavelength will decrease, and vice versa.
* Constant Speed: The velocity of sound in air is roughly constant at approximately 343 m/s at room temperature. However, it can be affected by factors like temperature and humidity.
Example:
Imagine a sound wave with a frequency of 440 Hz (the note A) and a wavelength of 0.78 meters. We can calculate the velocity:
* Velocity = 440 Hz x 0.78 m = 343.2 m/s (approximately the speed of sound in air)
