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.
