The frequency of beats produced when two tunning forks of frequencies 258Hz and 270Hz are sounded close to each other

Answer Details

When two tuning forks of slightly different frequencies are sounded close to each other, they produce what is called a beat. The beat frequency is the difference between the frequencies of the two tuning forks. In this case, the beat frequency can be calculated as follows: Beat frequency = |258 Hz - 270 Hz| = 12 Hz Therefore, the correct answer is 12Hz. When the two tuning forks are sounded together, they will produce a sound wave with a frequency that is the average of the two frequencies. However, since the frequencies are slightly different, the two sound waves will periodically reinforce and cancel each other out, producing the beat frequency that we hear. The beat frequency is the rate at which the sound waves reinforce and cancel each other out, and is equal to the difference between the frequencies of the two tuning forks.
