Answer:
The two value of the wavelength for the out of tune guitar is
Explanation:
From the question we are told that
The wavelength of the note is
The difference in beat frequency is
Generally the frequency of the note played by the guitar that is in tune is
Where is the speed of sound with a constant value
The difference in beat is mathematically represented as
Where is the frequency of the sound from the out of tune guitar
substituting values
The wavelength for this frequency is
For the second value of the second frequency
The wavelength for this frequency is
