Two violins produce frequencies of 293 Hz and 298 Hz. What beat frequency is heard? Note: this problem requires absolute accuracy. You must get the answer exactly correct. Number Units
What beat frequencies result if a piano hammer hits three strings that emit frequencies of 659.3, 293.6, and 440.0 Hz? (Enter your answers from smallest to largest.) You and a friend frequently play a trombone duet in a jazz band. During such performances it is critical that the two instruments be perfectly tuned. Since you take better care of your trombone, you decide to use your instrument as the standard. When you produce a tone that is known to be...
3. Three Strings A3= 220 HZ, E4=660 HZ, & E5=660 HZ, are sounded simultaneously. a) what are the frequencies of all the beat notes? b) Give the ratios of all the frequencies heard by the ear.
If two sources of sound at frequencies "f1" and "f2" are present, a listener may hear a beat frequency at f_beat = |f1 - f2|. Say your lab instructor turns on two such sources, and tells you f1 = 500 Hz, and that f2 is slightly higher frequency. You hear the combined sound level from the sources get louder and softer, and you measure that it takes 10 seconds for this cycle to repeat 20 times. What is the frequency...
A violin string is 40 cm long. It sounds the musical note A (440 Hz) when played without fingering.How far from the end of the string should you place your finger to play the note C (523 Hz)?
Two nearby trumpets are sounded together and a beat frequency of 8 Hz is heard. If one of the trumpets sounds at a frequency of 871 Hz, what are the two possible frequencies of the other trumpet? (Enter your answers from the smallest to the largest, in Hz, to three significant figures
Please explain and show how to do the exercise (at the bottom),
parts b and c. Explain what you are substituting in the Doppler

EXAMPLE 14.11 Sour Notes Goal Apply the beat frequency concept. Problem A certain piano string is supposed to vibrate ning, what beat frequency is observed by the assistant? at a frequency of 4.40 X 102 Hz. To check its frequency, Note: Assume all numbers...
You have 2 tuning forks in your hands; one plays the note D (297 Hz) and the other plays the note A (220 Hz). Your classmate plays a third fork with an unknown note and listens to the new combined frequency. Assuming that you can measure the combined frequency like 275 Hz when all three forks are played simultaneously, which of the following notes is most likely to correspond to the mysterious tuning fork a. C (264 Hz) b. F...
Consider a musical instrument that can be regarded as a long
pipe with both ends closed (see Fig. 1). Let the pipe length
L=0.250 m. Closed ends mean that you should have nodes at the two
ends. Assume sound speed to be v=330 m/s.
