Q26.A set of 20 tuning forks is arranged in a series of increasing frequencies. If each fork gives 4 beats with respect to the preceding fork and the frequency of the last fork is twice the frequency of the first, then the frequency of last fork is _____ Hz.
What This Question Tests
This question involves applying the concept of beats in a series of tuning forks and solving an arithmetic progression to find the final frequency.
Concepts Tested
Formulas Used
f_n = f_1 + (n-1)b
Beat frequency = |f1 - f2|
