Nettet13. aug. 2024 · When it comes to the speed of sound, a solid object will allow the vibration to move much faster since it has the most densely packed molecules. It will also make the sound the loudest. After solids, liquids have the highest speed of sound. And then finally gas, that included our air since it is made up of gasses. Nettet6. des. 2024 · In this lesson, we learned that sound travels in waves called sound waves. These waves vibrate molecules in air, water, and solids. The vibrations of these molecules create sounds.
