Name _____________________ Class ______________ Date _________Lab Report - Activity P28: Interference of Sound Waves - BeatsWhat Do You Think?In a typical classroom of science students, one or two people may play a guitar. They coulddescribe to you the phenomenon they are trying to eliminate in the process of tuning. Ask aguitar player to describe what they are listening to as they tune a guitar. Write a brief descriptionof what you hear when two slightly out-of-tune guitar strings are played at the same time.Analyzing the DataData TableTime (ms)Frequency (Hz)Individual Frequencies for Dual Function GeneratorGENERATOR 1GENERATOR 21. Calculate the beat frequency: υ beat= 1time2. Find the difference between the two individual frequencies and compare this to the beatfrequency.Beat Frequency (experimental) = HzBeat Frequency (theory) = |Frequency2 - Frequency1| = HzPercent difference between experimental and theoretical values =Question1. What are some factors that could account for the percent difference between experimentaland theoretical values?P28 ©1999 PASCO scientific p. 207
