True, but only for a particular medium. In other media, the relationships of
frequency and wavelength are different. i.e. where the speeds ("phase
velocities") of wave propagation are different.
But always: "phase velocity" = frequency times wave length at each particular
frequency. However, the "group velocity" of a packet of waves of many
frequencies which superpose to form pulses of various shapes can range from
near zero to very large numbers, but *always* less than c = 3 x 10^m/s.
Travel of a pulse on a string (a plucked string), or an object in space at
speeds greater than c is fascinating imagination, but is pure science fiction.
Although this is possibly more than retains your interest, the point is that
each frequency does not have a specific wavelength as Stanley asserts.
