A string under tension tau_(1) oscillates in the third harmonic at frequency f_(3), and the waves on the string have wavelength lambda_3, If the tension is increased to tau_(f)= 8tau_(i), and the string is again made to oscillate in the third harmonic, what then are (a) the frequency of oscillation in terms of f_3 and (b) the wavelength of the waves in terms of lambda_(3)?
