the possible frequencies of vibrations of the second string.
Answer to Problem 18R
Thepossible frequencies are,
Explanation of Solution
Given:
The frequency of one beat of a guitar string is 440 Hz. Another guitar produces 2 beats per second.
Introduction:
The frequency of beats is the difference between the frequencies of the two coinciding sounds.
Formula used:
The expression for frequency of beats is given by,
Here, fbeatsis the frequency of beats, f1 is the frequency of first guitar string and f2 is the frequency of another guitar string.
Calculation:
There are two possibilities of the frequency of beats,
Substituting the value of 440 Hz in f1 and 2Hz in fbeats in equation (2),
Or,
Conclusion:
Hence, the possiblefrequencies are,
