How does sound travel through different mediums?

Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as air, water and wood. When an object vibrates, it causes movement in the particles of the medium. This movement is called sound waves, and it keeps going until the particles run out of energy.

Why and how do sounds and light travel differently in different mediums?

Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. (Actual speeds are on the 2nd page)

Which material can sound travel the fastest?


What is the most resonant metal?


What is it called when a metal rings when it is hit?

Sonority (of a material) is the property of producing a ringing sound when struck. Most metals are sonorous. Therefore, they are used in many instruments (eg. cymbals and bells).

Why does metal ring when it is hit?

An object rings because it’s stiff but elastic. When you hit it, the energy propagates through it without loss. In a soft material, the energy is absorbed and turned into heat. In a stiff material, like glass or some metals, the energy manifests as waves, which move the air in a regular way that we hear as ringing.

Which metal is used for making bells?


Why bells are made of metals?

The reason that bells are made of metals is that metals are sonorous. Hence, metals can make the deep ringing sound, the sound of the bell you’re familiar with.

Why are the bells made of metal not of wood?

The bells are made by metals instead of wood because – Due to this property of the metals,a loud metallic sound is produced when we hit a piece of metal by any object. But,the wood doesn’t have any kind of sonorous property and that’s why when we hit wood by any object,a very dull sound is produced.

Why are electrical wires made of copper?

Why is copper used for most electrical wiring? The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor. Copper is also less oxidative than other metals.

Why bells Cannot be made of non metals?

Metals have the property of producing a ringing sound when struck. Therefore, metals are sonorous and have the property of “Sonority”. Non-metals however, are not sonorous and hence are not used in bells.
