If the wavelength remains constant and the frequency doubles, what happens to the wave speed?

Explanation:
The key idea is that wave speed is the product of frequency and wavelength: v = f × λ. If the wavelength stays the same and the frequency doubles, then the speed must double as well. In other words, keeping the spacing between crests fixed while twice as many crests pass per second means the wave travels twice as fast. This relationship shows how changing frequency affects speed when the wavelength is held constant.
