Here's why:
* Frequency refers to how many wave cycles pass a fixed point per second. It's measured in Hertz (Hz).
* Wavelength is the distance between two consecutive crests (or troughs) of a wave. It's measured in meters (m).
Think of it like this:
* Imagine a rope tied to a post. If you shake the rope quickly (high frequency), the waves created will be close together (short wavelength).
* If you shake the rope slowly (low frequency), the waves will be spread out (long wavelength).
The relationship between frequency (f) and wavelength (λ) is governed by the following equation:
Speed (v) = Frequency (f) x Wavelength (λ)
Where:
* Speed (v) is the speed at which the wave travels through the medium.
This equation tells us that the speed of a wave is constant for a given medium. Therefore, if the frequency increases, the wavelength must decrease to keep the speed constant.
Examples:
* Sound Waves: Higher frequency sound waves have shorter wavelengths, resulting in higher pitches. Lower frequency sound waves have longer wavelengths, resulting in lower pitches.
* Light Waves: Visible light has a range of wavelengths, from violet (shortest wavelength, highest frequency) to red (longest wavelength, lowest frequency).
In summary:
* Frequency and wavelength are inversely proportional.
* Higher frequency means shorter wavelength.
* Lower frequency means longer wavelength.
