Concept explainers
To Find: The beat frequency that can be heard.
Answer to Problem 55P
Explanation of Solution
Given:
Train car frequency,
The train car approached the station
Formula used:
Calculation:
The train is an observer and moving toward the source.
To calculate the beat frequency, use the Doppler effect,
Where,
Now, the beat frequency is the difference of frequencies,
The beat frequency is
Conclusion:
The beat frequency that can be heard, if the train car approached to the station is
