Answer:
396
Step-by-step explanation:
Given A tuning fork produces four beats per second with 49 cm and 50 cm when sounded with a sonometer. Find the frequency of the tuning fork.
Consider frequency of tuning fork f1 and sonometer f2
f1 + f2 = 4 + 4 = 8
So T(1/49 - 1/50) = 8
T(50 - 49/2450) = 8
T = 19,600 /49
T = 400 hz
Tuning fork frequency is T - 4 = 400 - 4 = 396 hz
