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 equation relating the velocity, wavelength and frequency of an electromagnetic wave is given byv=f λwhere v - velocity of the em wavef - frequency of the em wave andλ - wavelength of the em wave------------------------------------------------------------------------------------------------It is so important to know that velocity of light depends on the nature of the medium and does not depend on the wavelength.
velocity = frequency multiply wavelength Rearrange the equation to find the frequency
v=f/lambda
The wave speed equation proposes that: v = fw; where "v" is the wave's velocity, "f" is the wave's frequency, and "w" (more notably used as lambda) is the wave's wavelength. Manipulating the equation and solving for wavelength yields: w = v/f. Thus, if one knows both the velocity and frequency of a wave, he/she can divide velocity by frequency to determine the corresponding wave's wavelength.
The equation, as originally written by Erwin Schrodinger, does not use relativity. More complicated versions of his original equation, which do incorporate relativity, have been developed.For more information, please see the related link below.
velocity
c= f x h
The equation isv ≈ c
You can use the equation v=fw. that is velocity (in meters per second) equals the frequency (in hertz) times the wavelength (in meters). so you can find the velocity of a wave with the frequency and the wavelength.
It decreases.
C=f x h
