Question
The picture below represents a _____ wave.
- Transverse wave
- Longitudinal wave
- Sound wave
- Water wave
Hint:
A transverse wave is a wave in which the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave.
The correct answer is: Transverse wave
- A guitar string's motion shows a transverse wave.
- Because it oscillates up and down perpendicular to its axis of motion.
- Transverse wave has an alternating pattern of crests and troughs.
- So, the correct option is a.
