Size:  516.7 KB I know their speeds are different, but since it doesn't mention anything about their wavelength, how to prove they have different frequency (pitch)?

    Is this work on stationary waves? If so is it a fair assumption to assume that we can consider the first harmonic pattern produced by each wire?

    If so we know that c=2Lf where L is the length. Then we can rearrange equations to get a frequency equation. Then we can consider the change of mass per unit length on the frequency of the waves, as all other factors are constant.

    That is the only way i can think of tackling the question with no wavelength etc given.

    Id be open to anyone having a differing opinion
