Two tuning forks of frequency 256Hz and 260Hz are sounded close to each other. What is the frequency of the beats produced?

Answer Details

When two sound waves with slightly different frequencies are played together, they interfere constructively and destructively, resulting in a periodic variation of amplitude, which is called beats. The frequency of beats produced is equal to the difference between the frequencies of the two sound waves. In this case, the two tuning forks have frequencies of 256Hz and 260Hz, respectively. Therefore, the difference between their frequencies is: 260Hz - 256Hz = 4Hz So the beats produced have a frequency of 4Hz. Therefore, the answer is: 4Hz.
