Answer :
Answer: The correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.
Explanation:
There are two main types of waves:
1. Transverse Waves: These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in vacuum also. For Example: Light waves.
2. Longitudinal waves: These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in vacuum. For Example: Sound waves.
From the given options, the correct answer is the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.
When waves propagate in a medium, then the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.
What are sound waves?
A sound wave is caused by disturbances in the path of propagation of the particles. These disturbances can be caused in the medium like solid, liquid, and air.
There are two main types of waves namely - Transverse waves and longitudinal waves.
Transverse Waves - These waves are the waves where the particles in a medium travel perpendicular to the direction of the wave. These waves do not require a medium to travel and can travel in a vacuum also.
Longitudinal waves - These waves are the waves where the particles of the medium travel parallel to the direction of the wave and these waves require a medium to travel and hence, cannot travel in a vacuum.
Thus, we can conclude that the motion of the medium is parallel to a longitudinal wave and perpendicular to a transverse wave.
