Question

What happens to sound waves from an object as it moves toward you?(1 point) Responses

Answer 1

Suppose the object were stationary and emitting waves that had a distance of 1 m between crests - the receiver would receive waves that had a distance of 1 between crests

Suppose the object were moving towards the receiver, then there would no longer be 1 m between the crests as measured in the laboratory frame because of movement of the object.

Then the receiver would receive waves that were less than 1 m apart and would report a higher frequency than if the object were stationary,
