Answer:
There is only a beat frequency when the frequency heard (perhaps a tuning fork) is different from the frequency from the object in question (piano string, etc.).
The beat frequency equals the difference of the frequencies of the sources.
The piano tuner should adjust the tension in the wire to: C. decrease the amount of interference and decrease the beat frequency.
A wave can be defined as a disturbance created in a medium, which progressively transports energy from a source to another location without the transportation of matter.
Basically, some of the phenomenon and properties associated with waves include the following:
An interference refers to a phenomenon in which two (2) waves meet while traveling along the same medium and they superpose to produce a resultant wave with either a lower, greater, or the same amplitude.
In this scenario, a beat frequency is being heard by a piano tuner when using a tuning fork to tune a piano wire. Thus, the piano tuner should adjust the tension in the wire, so as to decrease the amount of interference and the beat frequency.
