When you add plasticine, the unknow frequency of the tuning fork reduces to either 301 or 295. With the known ruling fork, which condition satisfies the given data?
Hi there! I am having trouble with the following question:
Plasticine (which lowers the pitch) is added to one tine of the tuning forks of unknown frequency referred to in question #4 (initial frequency = 300 Hz possible frequencies 303 Hz or 297 Hz). The number of beats decreases to one(per second). What was the frequency of the unknown fork?
Well, i know how to calculate the beat difference, but I do not under stand which of the 303Hz or the 297Hz referred to question #4 are the correct initial frequencies before adding the Plasticine!!! Can some one explain that to me please!
Thank you for your time.
This is the only thing I don't understand >.< how do you determine that?!!!?!?!?!?!?!
Can you please explain!
Thank you for your time!
Btw here is question #4
Two tuning forks are sounded together, producing three beats per second. if the first fork has a frequency of 300 Hz , what are the possible frequencies for the other fork?
The answers are: 297Hz and 303Hz
