two tuning forks are struck at the same time. One tuning fork has a frequency 20hz while the second tuning fork has afrequency of 226hz.how many beats will result?
You get the 20 Hz, the 226 hz, the sum of the two and the difference of the two. The 20 and 226 are the original frequencies; the sum is one beat frequency and the difference is another beat frequency.
