Two guitarists attempt to play the same note of wavelength 6.50cm at the same time, but one of the instruments is slightly out of tune and plays a note of wavelength 6.51cm instead.
Beat frequency is = the difference of the frequencies
so f beat = 1/650-1/651
=2.3
= two beats per sec

Two guitarists attempt to play the same note of wavelength 6.92 cm at the same time, but one of the instruments is slightly out of tune and plays a note of wavelength 6.96 cm instead. What is the frequency of the beat these musicians hear when they play together? (Speed of sound in air is 344 m/s.) Hz
Two guitarists attempt to play the same note of wavelength 6.48 cm at the same time, but one of the instruments is slightly out of tune and plays a note of wavelength 6.52 cm instead. What is the frequency of the beats these musicians hear when they play together? Express your answer to two significant figures and include the appropriate units.
Algebra based physics 4. Two trumpeters attempt to play the same note of wavelength 0.868 m at the same time, but one of the instruments is out of tune. AsS a result, a beat frequency of 3.80 Hz is heard between the two instruments. The speed of sound in air is 343 m/s. a. What is the frequency of the desired note? a) What are the two possible frequencies of the out-of-tune note? b. b)
The Ohio State Marching Band (TBDBITL) is rehearsing for a half time show. They begin by tuning their instruments so that everyone plays with the same pitch. The lead trumpet player sustains an 'A' at 440 Hz. The band members join in one by one and if the new player is off pitch, a beat frequency is heard. (A) The second trumpet player comes in playing slightly out of tune at 443 Hz. What is the beat frequency created when...

Problem 4: Beats Two musicians are playing the same instruments. The first one emits the sound with correct wavelength 58 cm while the second one is off, and the wavelength is 5 mm longer. a) What is the frequency of the beats when they play together? b) By how much does the second musician need to change her instrument's wavelength so that the frequency of the beats is reduced to 1 Hz?

27. Two musicians play and hold a note that has a Temp is 10° C frequency of 287 Hz. A bicyclist rides away from one musician and approaches the other, moving at a constant speed of 13.4 m/s? The cyclist hears notes from the two musicians that undergo Doppler shitits in frequency. Calculate the two frequencies that the cyclist hears from the violins, f and f a. 12 b. What beat frequency is produce by the tones from the two...
