Question

you have three tuning forks with frequencies of 254 hz, 257 hz, 261 hz.

part a
what is the beat frequency if the tuning forks with frequencies of 254 hz and 257 hz are sounded together?
express your answer using three significant figures.
\\(f_{\text{beat, a}} =\\) hz

part b
what is the beat frequency if the tuning forks with frequencies of 257 hz and 261 hz are sounded together?
express your answer using three significant figures.
\\(f_{\text{beat, b}} =\\) hz

Explanation:

Define the beat frequency concept

Using the Wave Interference knowledge point

$$ f_{\text{beat}} = |f_1 - f_2| $$

Calculate the beat frequency for Part A

Using the Wave Interference knowledge point

$$
LATEXBLOCK0
$$

Calculate the beat frequency for Part B

Using the Wave Interference knowledge point

$$
LATEXBLOCK1
$$

Answer:

Question 1

\(f_{\text{beat, A}} = 3.00\)

Question 2

\(f_{\text{beat, B}} = 4.00\)
