As the ambulance approaches the woman, how will she perceive the pitch of the siren and why? Which of the following diagrams best ilustrates how light rays are reflected off a mirror? A. She will perceive a higher pitch because the speed of the sound waves is faster. A. B. The pitch she will perceive will be the same, only the volume of the sound is louder. C. She will perceive a higher pitch because the frequency of the sound waves is higher. D. The pitch she will perceive will be the same, only the intensity of the sound is greater. 5 The table shows the speed of sound in different media Speed of Sound (m/s) Media B.
