1.)Describe how the Doppler effect explains why a siren has a lower pitch as a fire engine moves away from you.


2.) How does a frequency of a wave relate to the energy of the wave?​

Answer 1

Answer: :)

1.) The Doppler effect is, the change in sound or light that occurs whenever there is motion between the source and its observer. The siren of the fire engine has a lower pitch as it moves away because the waves are now spread out causing a lower frequency and a lower pitch.

2.) Wave frequency is related to wave energy. Since all that waves really are is traveling energy, the more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.
