MP Board · Class 9 · Science · SoundWhy can sound waves not travel through a vacuum? Explain briefly.
Step-by-Step Solution
Sound waves are mechanical waves that require a material medium such as solid, liquid, or gas for their propagation. They travel through the vibration of particles of the medium transferring energy from one particle to the next. Since a vacuum contains no matter or particles to vibrate and transfer energy, sound waves cannot travel through a vacuum.
