Final answer:

Radar uses radio waves, while a passing siren emits sound waves, showcasing the Doppler effect.


Explanation:

The main difference between radar and a passing siren in terms of the Doppler effect is that radar uses radio waves, while a siren emits sound waves.

Radar functions by analyzing the returning radio waves' frequencies to determine the distance and speed of objects, such as airplanes or cars. On the other hand, a siren's sound changes pitch as it approaches or moves away from an observer, showcasing the Doppler effect in sound waves.
