Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
Opaque objects don't allow light to pass through them while translucent objects slow the passage of light but ultimately allow it to pass through.
It is called conductivity
A CD is not considered a translucent object. Translucent objects allow some light to pass through, but scatter it in different directions, making the object appear blurry or opaque. In contrast, a CD is reflective and opaque, as it does not allow light to pass through it.
A materiel that allows an electric charge to pass through it is an conducter (copper, for example)
P-waves are type of elastic wave, also called seismic waves, that can travel through gases (such as sounds), elastic solids and liquids, including the Earth. P-waves can be produced by earthquakes and recorded by seismometers. The name P-wave stands for primary wave, as the P-wave is the fastest among the elastic waves, compared to the S-waves.(Sources Wikipedia). Hope that helps! :D
Objects that let all light through are called transparent objects, like glass windows. Objects that only let some light through are called translucent, like a lamp shade, or a curtain. Objects that don't let any light through are called opaque, like a desk.
My teacher told me that light can travel through translucent object.
The object is opaque
An object that transmits light or allows light to pass through it is called a transparent object. Examples of transparent objects include glass, water, and plastic. These objects allow light to travel through them with minimal distortion or absorption.
Materials that allow light to pass through them are called transparent materials.
Objects that transmit light easily are called transparent. These objects allow light to pass through them with little or no distortion. Glass and clear plastics are common examples of transparent materials.
all of these
Objects that allow electricity to pass through them are called conductors. Conductors are materials that contain free electrons that can move freely in response to an electric field, facilitating the flow of electric current. Examples of conductors include metals like copper and aluminum.
opaque objects
When light cannot pass through an object, it is called opacity. This means that the material does not allow light to travel through it and blocks the transmission of light.
The name given to objects that do not cast a shadow in the presence of light is called translucent. Translucent objects allow light to pass through them, making them appear to have no shadow.
Materials that allow light to pass through them are called transparent materials. These materials do not absorb or reflect light, enabling light to travel through them with minimal obstruction. Examples include glass, water, and clear plastics.
