If a light wave is traveling at a constant speed and encounters a different medium, which statement best describes what will most likely happen to the wave
O The speed can decrease.

The Doppler effect is observed when a sound source is in motion relative to an observer, causing a shift in frequency perceived by the observer. When an ambulance is rapidly approaching, the frequency of the sound increases, leading to a higher pitch. Conversely, as the ambulance moves away, the frequency decreases, resulting in a lower pitch.
