The equation for beat frequency is as follows:
f_b = |f_2 - f_1|
Meaning the absolute value of the difference between 2 frequencies. But when you figure out the possiblilities of f_2, you analyze both -f_b and f_b, if you are using the absolute value because negative beat frequencies don't exsist, then why do you analyze the negative beat frequency? You calulate as:
f_2 = f_b + f_1
OR
f_2 = -f_b + f_1
I don't see why you should analyze the negative beat frequency if it doesn't exsist.
Someone please help soon.
