The beat frequency is 8Hz. What is f2 if f1 is 350Hz?
F2=350Hz +/- 8Hz
= 342Hz or 358Hz.
If the beat frequency increases at 340Hz then it means that f2 must be 358Hz.
Why??
To understand why f2 must be 358Hz if the beat frequency increases at 340Hz, we need to first understand what beat frequency means.
Beat frequency is the difference between two frequencies. In this case, the beat frequency is given as 8Hz.
Let's say f1 is 350Hz and f2 is an unknown frequency. The beat frequency is the difference between f1 and f2:
Beat frequency = f2 - f1
We are given that the beat frequency is 8Hz:
8Hz = f2 - 350Hz
To solve for f2, we rearrange the equation:
f2 = 8Hz + 350Hz
f2 = 358Hz
So, if the beat frequency is 8Hz, then f2 must be 358Hz.
