wave vector and frequency, which characterize the rapidity of this change, and which are respectively inverse of the wave length and wave period:.wave length and its period, which characterized the periodicity of the wave in space and time.It is a little bit as comparing apples and oranges: it is more meaningful to compare either So the longer the wavelength, automatically the less number of those waves can pass through in a second, and therefore the lower the frequency counted becomes. The frequency they pass through the street is 1 vehicle per second, assuming the speed in both lanes is always the same.
The wavelength of the limousine is 5 meters. The frequency the motorcycles pass through the street is 5 vehicles per second. In technical terms, this means the wavelength of the motorcycle is 1 meter. This means, on the right lane, only 1 limousine can pass by in one second, right? Because the limousine is longer.
Suppose we see that in 1 second, 5 motorcycles can pass through the left lane. The right lane is for 5-meter long limousines. The left lane is for 1-meter short motorcycles. They are automatically inversely related if the speed at which they move is the same for waves everywhere. The frequency is how many of these little waves can pass through in one second. The wavelength is how long each individual little wave is.
