One end of a long wire is fixed while a vibrator is attached to the other end. When the vibrator is energized, the types of waves generated in the wire are
stationary and longitudinal
stationary and transverse
progressive and transverse
progressive and longitudinal
Penjelasan
The vibrator is fixed at the end of the rope, hence, it is stationary. Also, the wave in this case, as well as the vibration are in the same direction, hence, it is longitudinal.
