Question

A tuning fork produces four beats per second with 49 cm and 50

Answer 1

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
