v = fλ
where:
* v is the wave speed (in meters per second, m/s)
* f is the frequency (in Hertz, Hz)
* λ is the wavelength (in meters, m)
Explanation:
* Wave speed (v): This is how fast the wave travels through a medium.
* Frequency (f): This is the number of wave crests (or troughs) that pass a fixed point in one second.
* Wavelength (λ): This is the distance between two consecutive crests (or troughs) of a wave.
Example:
If a wave has a frequency of 10 Hz and a wavelength of 2 meters, its speed is:
v = 10 Hz * 2 m = 20 m/s
This equation is applicable to all types of waves, including:
* Electromagnetic waves: Light, radio waves, X-rays, etc.
* Mechanical waves: Sound waves, water waves, etc.
