7 Questions
What is the frequency of the sound being emitted by the stationary source?
500 Hz
What is the typical velocity of sound in air at room temperature?
340 m/s
What is the equation used to calculate the frequency observed?
frequency observed = frequency of source * velocity of observer / velocity of sound
What happens to the frequency observed when the observer is moving towards the stationary source?
It increases
What effect does a larger numerator have on the frequency observed?
It increases
What is the frequency observed by the observer when walking towards the stationary source at a speed of 10 m/s?
514.70 Hz
How does the frequency observed change when the source is moving towards the observer compared to when the observer is moving towards the source at the same speed?
The frequency observed is higher when the observer is moving towards the source
