Question

8/10
what changes in a wave when it moves from one
medium to another?
frequency only
neither frequency nor wavelength
wavelength only
frequency and wavelength

Explanation:

When a wave moves from one medium to another, its frequency remains constant as it is determined by the source of the wave. However, the speed of the wave changes depending on the medium. Using the wave equation \(v = f\lambda\) (where \(v\) is speed, \(f\) is frequency, and \(\lambda\) is wavelength), since \(f\) is constant and \(v\) changes, the wavelength \(\lambda\) must change.

Answer:

Wavelength only
