Detailed Solution


Concept: We hear sound or noise in our daily lives, but we have no idea how the sound travels from one location to another. So, because sound travels in the shape of a wave, we refer to it as a sound wave rather than just sound in physics.
When a wave moves through a medium, the particles vibrate, and sound is created as a result of the vibrations. That is why sound waves require a medium to pass through. As a result, it is unable to go through a vacuum.
Solid > liquid > gases > vacuum is the speed order of sound waves.
The speed of sound is greatest in solids, and the sound wave travels quickly through steel.
Hence, option 4 is correct.
