Question

A tuning fork with a frequency of 440Hz produces 4 beats per second when sounded together with a violin string. What was the original frequency of the string if a slight increase in tension produces fewer beats per second than before?

Answer 1

if still have query then plzz comment. Thank you. ?

solution: Cuven, fergency of tuning fork, f. = 440 Hz & Beat frequency 06= 4 M2 As 4 = 1f-fil - where to us frequency of string Now, I in tension in stering Tin foregereng for I % it means for must be shorter than f. 2 Vo = -(fr-f.) b=f. - fa 2 fr = f.-U 2 fr = 440-4 & fa = 436 Hz is the required anginal Frezerency.
