Melissa is studying the distinct characteristics of waves and has discovered that when the wavelength of a wave increases, the frequency decreases. In what circumstance does the speed of a wave alter? (1 point) Responses when the wave comes into contact with a different medium when the wave comes into contact with a different medium when there is a change in the amplitude of the wave when there is a change in the amplitude of the wave when a wave bounces off a surface when a wave bounces off a surface when there is a change in the mass of the wave
