In the case of a wave, the speed is the distance traveled by a given point on the wave (such as a crest) in a given interval of time. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. wave is a disturbance that moves along a medium from one end to the other. If one watches an ocean wave moving along the medium (the ocean water), one can observe that the crest of the wave is moving from one location to another over a given interval of time.
If the crest of a slinky wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2 m/s. Because wavelength (Î») and period (T) are units of distance and time, the above equation may be written as follows: v = Î» f. By this, you can see the wavelength and frequency are inverses of each other.
