what is the meaning of S waves
Answer (1)
Answer:S waves, or secondary waves, are a type of seismic wave that travels through the Earth's interior. They are characterized by their transverse motion, meaning that the particles they pass through move perpendicular to the direction of wave propagation. This is in contrast to P waves, or primary waves, which are longitudinal waves and cause particles to move parallel to the direction of wave propagation. Here's a breakdown of key characteristics of S waves: - Motion: Transverse (particles move perpendicular to wave direction)- Speed: Slower than P waves- Travel: Through solids only (cannot travel through liquids or gases)- Detection: Recorded by seismographs, appearing after P waves- Importance: Provide valuable information about the Earth's internal structure Why can't S waves travel through liquids? S waves require a rigid medium to propagate. The molecules in a solid are tightly packed and can transmit the shearing motion necessary for S waves. Liquids, on the other hand, have less rigidity and their molecules can easily slide past each other. This prevents the transmission of the transverse motion characteristic of S waves. The significance of S waves S waves are crucial for understanding the Earth's internal structure. Their inability to travel through the Earth's liquid outer core provides evidence for this core's existence and composition. Furthermore, the speed and path of S waves can be used to map the Earth's layers and determine the composition and properties of different rock types.sana makatulong (correct me if I'm wrong)
