Both wood and cardboard are examples of opaque materials that do not allow light to pass through them. This is because their molecular structure is dense and does not allow light to penetrate, making them effectively block the transmission of light.

Why can't sound travel easily through some materials?

Sound needs a medium to travel. It cannot travel through a vaccum.


What materials will sound travel through?

Sound waves will travel through gases, liquids, and solids. Sound waves cannot pass through a vacuum.


Can sound travel easily through a vacuum?

No, sound cannot travel through a vacuum because sound waves require a medium, such as air, water, or solid materials, to propagate. In a vacuum, there is no medium for the sound waves to travel through, so they cannot propagate.


What materials can light not travel through?

Light cannot travel through an opaque material. The word "opaque" simply means that a substance isn't transparent or translucent. So most everyday materials, like wood, plastic, iron, and people are all opaque.


Can heat travel through all materials?

No, heat cannot travel through all materials. Some materials are insulators, which do not allow heat to pass through easily, while others are conductors that allow heat to pass through them readily. The ability of a material to conduct heat is determined by its thermal conductivity.


What can light travel through that sound cant travel through?

Light can travel through a vacuum, such as outer space, where sound cannot travel as it requires a medium like air, water, or a solid to propagate. Light can also travel through transparent materials like glass or air, while sound is mostly blocked or absorbed by these materials.


What types of materials can sound not travel through?

Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.


What is a material that light can't travel through?

There is no known material that light cannot travel through. However, materials such as lead and thick concrete can significantly attenuate or absorb light, making them almost opaque to visible light.


Which is true heat can travel well through all materials or heat can travel well through some materials?

Some, but not all. Some materials are insulators- heat does not travel well through them.


What types of materials do s waves pass through?

S waves, also known as secondary waves, can only pass through solid materials such as rocks and metals. They cannot travel through liquids or gases.


What medium sound waves travel through?

Sound waves can travel through any matter- liquid, gas or solids. The denser the matter, the faster the sound travels. It cannot travel through vacuum- a vacuum is an absence of matter.


How fast do sound waves travel through a vacuum?

You'd have to say that the speed of sound waves in vacuum is zero, becausesound can't travel through vacuum at all. Not even an inch. Sound needs amaterial substance to travel through.
