Originally the frequency of the wave in two strings are the same, if the tension of one string is changed by 1%, what is the freuency of beats?

thank u in ad:)

## one problem about beat

v = \lambda f where f is the frequency of the string and \lambda is the wavelength

so, if the tension of the string is changed by 1% F = 1.01 F_0 where F_0 is the original force/tension.... plug that into the equations above, solve for f.

f-f_0 gives the frequency of the beats (f_0 is the original frequency)

the link explains how they're derived.
