Question

A 440 Hz tuning fork is sounded together with the A string on a guitar, and 21 beats are heard in 3.0 s. (a) What are the possible frequencies of the guitar string? (b) When an elastic band is wrapped tightly around one of the tuning fork's prongs, a new frequency of 2.0 Hz is heard. What is the frequency of the guitar string? Explain. (6 marks)

Step 1

Given F_beat = 21 beats in 3.0 s and f1 = 440 Hz, we can calculate the possible frequencies of the guitar string: f2 = 440 ± 21/3 = 440 ± 7 = 433 Hz or 447 Hz Show more…
