Here's why:
* The relationship: The velocity of a wave (v), its wavelength (λ), and its frequency (f) are related by the following equation:
v = fλ
* Constant wavelength: If the wavelength (λ) remains constant, and the velocity (v) increases, the only way to maintain the equality in the equation is for the frequency (f) to also increase.
In simpler terms:
Think of it like this: Imagine a line of cars moving down a road. If the cars start moving faster (increased velocity), but the distance between each car (wavelength) remains the same, then more cars will pass a certain point each minute (increased frequency).
