Answer» Answer: Question: Tuning fork A produces 4 beats with tuning fork B of frequency 346 Hz. When tuning fork A is FILED, the NUMBER of beats heard is 6 per SEC. Find original frequency of Tuning fork A. Given: Beat frequency = 4 Hz. Frequency of B = 346 Hz. If Tuning fork A is filed, then beat frequency becomes 6 To find: Frequency of Tuning fork A. Concept: We don't know if frequency of Tuning fork A is greater or lesser than that of Tuning Fork B So, either of the 2 Equations can form : $1) \: \: f_{a} - 346 = 4$ $2) \: 346 - f_{a} = 4$ Now , we know that if a tuning fork is filed, then it's frequency increases . $So \: if \: value \: of \: f_{a} \: increases ,\: as \\ \: per \: the \: <klux>QUESTION</klux> ,\: the \: beat \: frequency \\ is \: also \: increasing.$ This is possible only in Equation (1) So taking Equation (1) in consideration: $\: \: f_{a} - 346 = 4$ $= > f_{a} = 346 + 4 = 350 \: hz$ So final answer is 350 Hz.

Answer:

Question:

Tuning fork A produces 4 beats with tuning fork B of frequency 346 Hz. When tuning fork A is FILED, the NUMBER of beats heard is 6 per SEC. Find original frequency of Tuning fork A.

Given:

Beat frequency = 4 Hz.

Frequency of B = 346 Hz.

If Tuning fork A is filed, then beat frequency becomes 6

To find:

Frequency of Tuning fork A.

Concept:

We don't know if frequency of Tuning fork A is greater or lesser than that of Tuning Fork B

So, either of the 2 Equations can form :

$1) \: \: f_{a} - 346 = 4$

$2) \: 346 - f_{a} = 4$

Now , we know that if a tuning fork is filed, then it's frequency increases .

$So \: if \: value \: of \: f_{a} \: increases ,\: as \\ \: per \: the \: <klux>QUESTION</klux> ,\: the \: beat \: frequency \\ is \: also \: increasing.$

This is possible only in Equation (1)

So taking Equation (1) in consideration:

$\: \: f_{a} - 346 = 4$

$= > f_{a} = 346 + 4 = 350 \: hz$

So final answer is 350 Hz.
