Question
Two tuning fork when sounded together produces 5 beats per second. The first tuning fork is in resonance with 16.0 cm wire of a sonometer and second is in the resonance with 16.2 cm wire of the same sonometer then the frequencies of the tuning forks are :
Options
A.100 Hz, 105 Hz
B.200 Hz, 205 Hz
C.300 Hz, 305 Hz
D.400 Hz, 405 Hz
Solution
f1 - f2 = 5 ⇒ 
= 5
⇒
= 5
⇒ f1 =
= 400Hz
= 5⇒
= 5⇒ f1 =
= 400Hz Create a free account to view solution
