[tex]\boxed{\sf\green{✓}}[/tex] The statement “Sound doesn't need a medium to travel through”, is [tex]\bold{\red{false}}[/tex].
[tex]\boxed{\sf\green{✓}}[/tex] Sound requires a medium to propagate.
❏ Sound is a mechanical wave that travels through the vibration of particles in a medium.
❏ Without a medium, such as air, water, or solid materials, sound cannot travel.
❏ In a vacuum, where there are no particles, sound cannot propagate because there is no medium for the vibrations to travel through.
❏ The speed of sound depends on the properties of the medium it is traveling through, such as the density and temperature.
❏ Sound travels fastest through solids, followed by liquids, and then gases. This is because the particles are more closely packed in solids, allowing sound waves to propagate more efficiently.
❏ For example, sound travels at around 343 m/s in air at 20°C, but 1,482 m/s in fresh water and 5,960 m/s in steel.
