A pair of tuning forks of frequencies
Rank from greatest to least the beat frequencies produced by the following pairs of tuning forks.
(A)
(B)
(C)
(D)
To rank the beat frequency of the given pairs of frequencies.
Answer to Problem 23A
1: (C) f1= 200 Hz, f2= 208 Hz
2: (B) f1= 300 Hz, f2= 305 Hz
3: (A) f1= 650 Hz, f2= 654 Hz
4: (D) f1=800 Hz, f2=801 Hz
Explanation of Solution
Given info:
The frequency pairs are
Formula used:
The beat frequency is
Calculation:
Substituting the given values, we get
Conclusion:
Thus, the rank of the beat frequency from greatest to least is
1: (C) f1= 200 Hz, f2= 208 Hz
2: (B) f1= 300 Hz, f2= 305 Hz
3: (A) f1= 650 Hz, f2= 654 Hz
4: (D) f1=800 Hz, f2=801 Hz
