Doppler Effect Flashcards
1
Q
What is the Doppler Effect?
A
As a source emitting a certain frequency approaches an observer the frequency is perceived as higher when the source moves away the frequency is observed to be lower.
2
Q
vs is…
A
speed of source
3
Q
fo is ….
A
frequency of observer
4
Q
fs is ….
A
frequency of source
5
Q
vo is ….
A
speed of observer
6
Q
If the observer is stationary, and the source is approaching the observer, you must ________.
A
Subtract in the denominator, to get a larger number which correlates to a higher frequency.
7
Q
If the observer is not stationary and is moving away from the source (stationary), you must _______.
A
Subtract in the numerator, to get a smaller number is correlates to a lower observed frequency.
