In 3 setences explain if the tension remains constant and the frequency increases, what happens to the wavelength?

Make it look like a 8th grader wrote it

Make sure no one can find this

Answer 1

When the tension stays the same and the frequency increases, the wavelength actually gets shorter. This is because a higher frequency means more waves are passing by in a given time, so the waves have to be closer together. So, if the tension doesn’t change but the frequency goes up, the wavelength decreases.
