Question 22 Marissa is learning about the unique properties of waves. She has learned that whenever the wavelength of a wave increases, the frequency of the wave decreases. When does the speed of a wave change? when a wave is reflected off a surface when the wave encounters a new medium C when the mass of the wave changes when the amplitude of the wave changes B.
