MP Board · Class 9 · Science · SoundExplain why sound travels faster in solids than in liquids and gases.
Step-by-Step Solution
Sound is a mechanical wave that propagates through the vibration of particles in a medium. In solids, atoms and molecules are tightly packed together with very strong intermolecular forces, allowing elastic deformation energy and vibrations to transfer rapidly from one particle to the next. In gases and liquids, particles are much farther apart and weakly bound, making energy transfer slower. Therefore, sound travels fastest in solids, moderate in liquids, and slowest in gases.
