Q
Q: If a sound source moves towards a stationary observer, what happens to the frequency heard by the observer?
Solution:
As the sound source approaches, the frequency increases due to the Doppler effect.
Steps: 5
Show Steps
Step 1: Understand that a sound source is something that makes noise, like a moving car or a train.
Step 2: Know that a stationary observer is someone who is not moving, like a person standing on the sidewalk.
Step 3: Recognize that when the sound source moves towards the observer, the sound waves get compressed.
Step 4: Realize that compressing the sound waves makes them closer together, which increases the frequency.
Step 5: Understand that a higher frequency means a higher pitch of sound, so the observer hears a higher sound as the source approaches.
