Find the minimum number of different beat frequencies

Reference no: EM13689908

Here is the problem which I am struggling on, please help me!

Problem: You have 21 tuning forks that oscillate at close but different frequencies. What are the

(a) maximum and

(b) minimum number of different beat frequencies you can produce by sounding the forks 2 at a time, depending on how the frequencies differ?

Show all work, use additional paper if necessary.
