## Homework Statement

Two tuning forks 384Hz and 256Hz.

The question asks - would the sound of the combined frequencies be more similar to the 256 or 384Hz tuning fork. Estimate the frequency of the complex wave (noting that the pattern is repeated over three times).

We are given two CRO traces (one 256Hz and one 384Hz tuning fork trace) and at the bottom of the CRO trace picture there appears to be a scale of 0.25 V/Div 5.005 ms/Div

## Homework Equations

384Hz - 256Hz = will give you a beats per minute of 128

384Hz + 256/2 = will give you 320Hz at which the ear can hear.

However I cannot locate an equation that will assess whether the combined sound is closer to 256 or 384Hz.

## The Attempt at a Solution

As above
