Demonstrating Beat Frequency - A Video Project by Bo

Bo presents a tutorial on beat frequency, starting with a demonstration using 440 Hz and 441 Hz tones. The beat frequency is explained as the absolute difference between two frequencies, resulting in a periodic increase and decrease in amplitude. The video illustrates how wave interference causes beats and shows a waveform representation. A practical application is tuning musical instruments, like a guitar, using beat frequency to ensure harmonics are in tune. The tutorial concludes with a summary of the concepts covered.

What is beat frequency and how is it produced?

Explain the relationship between the frequencies of two tones that produce a beat frequency.

Describe how wave interference contributes to the phenomenon of beat frequency.

How can beat frequencies be used in tuning musical instruments?

What happens when one of the strings in a musical instrument is slightly out of tune?
