Speed (v) = Frequency (f) x Wavelength (λ)
Here's what each variable means:
* Speed (v): The speed of the wave, usually measured in meters per second (m/s).
* Frequency (f): The number of wave crests passing a fixed point in one second. It's measured in Hertz (Hz), which is equivalent to cycles per second.
* Wavelength (λ): The distance between two successive crests (or troughs) of a wave. It's measured in meters (m).
Example:
Let's say you have a wave with a frequency of 10 Hz and a wavelength of 2 meters. To find the speed:
* v = f x λ
* v = 10 Hz x 2 m
* v = 20 m/s
Therefore, the speed of the wave is 20 meters per second.
Important Notes:
* This formula works for all types of waves, including sound waves, light waves, and water waves.
* The speed of a wave can be affected by the medium it travels through. For example, sound travels faster in solids than in liquids, and faster in liquids than in gases.
* The frequency and wavelength of a wave are inversely proportional. This means that if the frequency increases, the wavelength decreases, and vice versa.
