Find what was the frequency of her violin

Reference no: EM13548378

1) A violinist is tuning her instrument to concert A (440Hz). She plays the note while listening to an electronicaly generated tone of exactly 440 Hz and hears 3.00 beats a second.

A: What two possible frequencies could be coming from the violin?

B: Now, when she tightens her violin strings slightly she hears 4.00 beats per second. What was the frequency of her violin when she heard 3.00 beats a second?
