Answer: The correct answer is Option A.
Explanation:
Waves are characterized into two types:
- Transverse wave: These waves are the waves where, particles of the medium travel perpendicularly to the direction of the wave. These waves do not require any medium to travel and can travel in vacuum also. For Example: Light waves.
Longitudinal waves: These waves are the waves, where particles of the medium move in the direction of the wave which means that the particles move parallel to the direction of the wave. These waves requires a medium to travel. For Example: Sound Waves.
Hence, the correct answer is Option A.
