[SOLVED] Calculating Beats
A person has two audio frequency generators with which to demonstrate beats. One generator is set to 1000Hz and the other to 998Hz. How many beats will be heard in 10s?
f = number of beats/time
number of beats = time/f
= 1000Hz/10s
= 100Hz
number of beats = time/f
= 998Hz/10s
=99.8Hz
Then I subtracted the two, getting 0.2 beats, which is most utterly wrong.

Homework Equations
f = number of beats/time
The Attempt at a Solution
number of beats = time/f
= 1000Hz/10s
= 100Hz
number of beats = time/f
= 998Hz/10s
=99.8Hz
Then I subtracted the two, getting 0.2 beats, which is most utterly wrong.
