If a piano tuner hears 3 beats each second when listening to a 8 Hz tuning fork and a single string on the piano which is of higher frequency.. What is the frequency of the single string from the piano?
To find the frequency of the single string on the piano, we can first calculate the beat frequency between the tuning fork and the string.
The beat frequency is the difference between the frequencies of two sounds. In this case, the tuning fork has a frequency of 8 Hz.
Given that the piano tuner hears 3 beats every second, we know that the beat frequency is 3 Hz (3 beats/second).
Now, we can determine the frequency of the string by adding or subtracting the beat frequency from the frequency of the tuning fork.
Since the tuner hears 3 beats each second, the frequency of the string must either be 8 + 3 = 11 Hz or 8 - 3 = 5 Hz.
Therefore, the frequency of the single string on the piano can be either 11 Hz or 5 Hz.
