- A tuning fork of unknown frequency makes 3.00 beats per second with a standard fork of frequency 384 Hz. The beat frequency decreases when a small piece of wax is put on a prong of the first fork.What is the frequency of this fork?A violin string ? = 31.6 cm long and ? = 0.65 g⁄m linear mass density is tuned to play a La4 note at 440.0 Hz. This means that the string is at its fundamental oscillation mode, that is, you will be on that note without placing a finger on it. From this information: A. Calculate the tension in the string that keeps it in tune.A guitar string produces 3 beats/s when sounded with a 359 Hz tuning fork and 8 beats/s when sounded with a 364 ?z tuning fork. What is the vibrational frequency of the string?

What will be the beat frequency in this case?
- A tuning fork B produces 8 beats per with another tuning fork C of second frequency 512 Hz. When the prongs of B are loaded with a little wax., the number of beats decreased to 6 per second. What was the frequency of fork B before it was loaded ?A tuning fork P produces 5 beats with another tuning fork Q whose frequency is known to be 284Hz. Deduce the frequency of the fork P.A loudspeaker has a frequency of 1000Hz to 2000Hz. An open open pipe is near the loudspeaker. The pipe is 45.7cm in length and the speed of sound is 344m/s. What are the frequencies in the range above that are in resonance?
