Wavespeed = frequency x wavelength
Frequency = Wave speed / Wavelength.
Speed(v) = wavelength(λ) x frequency(f).
Any wave. Of you have a wave (light, water etc.), it will have a frequency and a wavelength. Multiply these and you get the speed at which the wave is moving.
The speed or velocity of a wave is equal to the wavelength times the frequency. The period (amount of time for one wavelength to occur) is equal to 1 over the frequency (the inverse of its frequency).
velocity = frequency multiply wavelength Rearrange the equation to find the frequency
Frequency = Wave speed / Wavelength.
wave speed= frequency/wavelenth
Wave speed wavelength times frequency.
wave speed= wave length * frequencyv=fa
The last bit of your question confused me a little!? :P ... But I think you are referring to the 'The Wave Equation'. Wave Speed (v) in m/s = Frequency (f) in Hz * Wave Length (λ) in m This equation relates the speed of a wave to its frequency and wavelength
Speed = Frequency * Wave length.
speed= frequency x wavelength
A wave equation is an equation that repeats y-values infinately creating a wave like pattern, a good example is the sine wave: http://en.wikipedia.org/wiki/Sine_wave
Speed(v) = wavelength(λ) x frequency(f).
For a single wave: Speed = (frequency) x (wavelength) Frequency = (speed) / (wavelength) Wavelength = (speed) / (frequency)
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
they are related by the equation velocity=frequency*wavelength
