Here's why:
* Wave Speed: The speed of a wave is determined by the medium it travels through. For example, sound travels faster in solids than in air.
* Wavelength: The wavelength is the distance between two consecutive crests (or troughs) of a wave.
* Frequency: The frequency is the number of waves that pass a point in a given time (usually measured in Hertz, Hz).
The relationship between these three is:
Speed = Wavelength x Frequency
Therefore, if the speed is constant, a longer wavelength means the frequency must be lower to maintain the equation.
Think of it like this:
Imagine a rope. If you shake the rope slowly, you create long waves (long wavelength). If you shake it quickly, you create short waves (short wavelength).
The faster you shake the rope (higher frequency), the shorter the waves become.
