In case of longitudinal waves, the particles of medium vibrate:a)In th...
Particles of medium vibrate in the direction of wave propagation.
Explanation:
Longitudinal waves are a type of mechanical waves where the particles of the medium vibrate parallel to the direction of wave propagation. These waves are characterized by compressions and rarefactions, where particles move back and forth in the same direction as the wave.
Particles move in the same direction as the wave:
When a longitudinal wave travels through a medium, the particles of the medium move in the same direction as the wave. This means that as the wave moves forward, the particles also move forward in a back-and-forth motion. This can be observed in various examples of longitudinal waves such as sound waves and seismic waves.
Compressions and rarefactions:
In a longitudinal wave, regions of high particle density are called compressions, while regions of low particle density are called rarefactions. As the wave passes through the medium, the particles in the compressions are pushed closer together, while the particles in the rarefactions are spread apart. This compression and rarefaction pattern continues as the wave propagates through the medium.
No side-to-side motion:
Unlike transverse waves, where particles move perpendicular to the direction of wave propagation, longitudinal waves do not exhibit any significant side-to-side motion. The motion of particles in a longitudinal wave is limited to back-and-forth vibrations parallel to the direction of the wave.
Conclusion:
In summary, the correct answer is option 'A' - In the case of longitudinal waves, the particles of the medium vibrate in the direction of wave propagation. This unique characteristic of longitudinal waves distinguishes them from transverse waves and is fundamental to their behavior and properties.
