* Speed (v): The speed of a wave is how fast it travels through a medium.
* Wavelength (λ): The wavelength is the distance between two successive crests or troughs of a wave.
* Frequency (f): The frequency is the number of wave cycles passing a point in a given time.
These three are related by the equation:
v = fλ
Let's break down what happens when speed and wavelength decrease:
* Decreasing Speed: If the speed of the wave slows down (v decreases), and the wavelength stays the same, the frequency must also decrease to maintain the balance in the equation.
* Decreasing Wavelength: If the wavelength decreases (λ decreases), and the speed stays the same, the frequency must increase to maintain the balance in the equation.
In summary, when both the speed and wavelength of a wave decrease, the frequency of the wave increases to maintain the relationship between speed, wavelength, and frequency.
Example: Imagine a rope being shaken. If you shake it slower (lower speed), the waves will be further apart (longer wavelength). If you shake it faster (higher speed), the waves will be closer together (shorter wavelength).
Note: The type of wave (e.g., sound wave, light wave) will influence how the changes in speed and wavelength affect the wave's properties.
