    What is the expected period of beats formed when two tuning forks sound simultaneously and have the frequencies f1= 250Hz and 242Hz? please help

    There are several ways to solve such homework problems. What have you tried so far, and where did you get stuck?

    what I did is subtract and add the two frequencies then divided by 1.....1/f=T, where T is period.
    I got 2.03*10^-3s and 0.125s...
    Is it right?
