Three tuning forks with unknown frequencies f_1,f_2 and f_3 are vibrated. 5 beats per second are heard when f_1 and f_2 are vibrated, 6 beats per second forf_1 and f_3 while 7 beats per second forf_2 and f_3. If f_2 isloaded with wax, number of beats for f_2and f_3decreases while for f_1 and f_2 increases. Find tuning forks shaving maximum frequency and minimum frequency in terms of f_2.
