Hello.
I think I have the answer to the following question, but I'm not sure if I got the concept.
You have a standard tuning fork whose frequency is 262 Hz and a second tuning fork with an unknown frequency. When you tap both of them on the heel of one of your sneakers, you hear beats with a frequency of 4 per second. Thoughtfully chewing you gum, your gum, you wonder whether the unknown frequency is 258Hz or 266Hz. How can you decide?
Of course, the beat frequency is the absolute value of the difference between the two frequencies, but in order to decide whether the unknown would be four more or four less than the standard, I get lost here. A hint would be really appreciated. Help!
-thank you very much for your time.
