Doppler Effect Sign Convention
Asked by Siddhant Misra | 03 Apr, 2011, 11:17: PM
Expert Answer
Whenever there is a relative motion between a source of sound and the listener, the apparent frequency of sound heard by the listener is different from the actual frequency of sound emitted by the source.
When the distance between the source and listener is decreasing the apparent frequency increases. It means the apparent frequency is more than the actual frequency of sound. The reverse is also true.

Sign convention : All velocities along the direction S to L are taken as positive and all velocities along the direction L to S are taken as negative.
Hope this helps.
