## v=f×λv = f \times \lambdav=f×λ

v=f×λv = f \times \lambdav=f×λ

Where:

- vvv is the speed of sound in the medium (measured in meters per second, m/sm/sm/s).
- fff is the frequency of the sound wave (measured in hertz, HzHzHz).
- λ\lambdaλ is the wavelength (measured in meters, mmm).

**Explanation:**

**Frequency (fff)**: The number of oscillations or cycles that a sound wave completes in one second.**Wavelength (λ\lambdaλ)**: The distance between two consecutive points in phase on the wave, such as from crest to crest or trough to trough.**Speed of Sound (vvv)**: The speed at which sound waves travel through a medium, like air, water, or steel. In air at room temperature, this speed is approximately 343 meters per second.

**Example:**

If the speed of sound in air is 343 m/s343 \, m/s343m/s and the frequency of the sound wave is 440 Hz440 \, Hz440Hz (which is the standard pitch for musical note A), then the wavelength λ\lambdaλ can be calculated as:

λ=vf=343 m/s440 Hz≈0.78 m\lambda = \frac{v}{f} = \frac{343 \, m/s}{440 \, Hz} \approx 0.78 \, mλ=fv=440Hz343m/s≈0.78m

This means the wavelength of a 440 Hz sound wave in air is about 0.78 meters.
