Answer :
Final answer:
Frequency is the measurement of the number of cycles of a wave that pass a point in one second. In the context of a siren's sound wave, the provided options A) 10000 peaks B) 20000 peaks C) 30000 peaks D) 40000 peaks could each represent possible frequencies, but it's impossible to determine the exact frequency without knowing the time period over which these peaks occur.
Explanation:
In physics, the frequency of the siren, or any other sound wave, refers to the number of complete cycles or oscillations of the wave that pass a specific point in one second. It is generally measured in Units of Hertz (Hz). The options provided: A) 10000 peaks B) 20000 peaks C) 30000 peaks D) 40000 peaks, each represent a possible frequency of a siren, however without knowing the time period over which these peaks occur, it wouldn't be possible to determine the frequency of the siren.
