Fundamental frequency of a stretched sonometer wire is `f_(0)`. When its tension is increased by `96%` and length drecreased by `35%`, its fundamental frequency becomes `eta_(1)f_(0)`. When its tension is decreased by `36%` and its length is increased by `30%`, its fundamental frequency becomes `eta_(2)f_(0)`. Then `(eta_(1))/(eta_(2))` is.
