Answer Details
When a vibrator is energized and attached to a long wire, it generates waves that propagate through the wire. The nature of these waves depends on the type of vibration produced by the vibrator. If the vibrator produces a transverse vibration, then the waves generated in the wire will also be transverse. If the vibrator produces a longitudinal vibration, then the waves generated in the wire will also be longitudinal.
Now, if the vibrator is attached to one end of a long wire which is fixed at the other end, the waves generated in the wire will be progressive because they will travel through the wire in a particular direction. Therefore, the correct answer is "progressive and transverse".
