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?

A. stationary and longitudinal
B. stationary and transverse
C. progressive and transverse
D. progressive and longitudinal

Correct Answer:

Option A – stationary and longitudinal

Explanation

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.
