Speed= Wavelength x Period

Speed = Wavelength/Frequency

|
Speed= Wavelength x Frequency
|
Detailed explanation-1: -The speed of a wave can be found using the equation v=f, or velocity = wavelength x frequency.
Detailed explanation-2: -Speed is distance over time, so v = / T. The frequency, f, is 1/T, so the equation relating wave speed, frequency, and wavelength is v = f .
Detailed explanation-3: -They are all related by one important equation: Any electromagnetic wave’s frequency multiplied by its wavelength equals the speed of light. We can use this relationship to figure out the wavelength or frequency of any electromagnetic wave if we have the other measurement.
Detailed explanation-4: -So in a time of one period, the wave has moved a distance of one wavelength. Combining this information with the equation for speed (speed = distance/time), it can be said that the speed of a wave is also the wavelength/period.
