Air.
it cant travel through light.
Light travels faster through liquid than through solid. The speed of light in a medium is determined by the refractive index of the material, which is lower in liquid compared to solid materials.
Light travels much faster than sound, through wood.
An opaqe object. NO light can travel through it at all.
Light can travel through transparent and translucent glass.
When light cannot travel through a material, it has been absorbed or blocked by the material. This typically occurs when the material is opaque and not transparent or translucent.
Air.
Sound and Light can travel through space.
Light will not travel through an opaque sponge.
Sound requires the physical motion of material. Light doesn't.
A material that light can travel through is called a transparent material. These materials allow light to pass through without scattering or being absorbed. Glass, air, and water are examples of transparent materials.
Light can travel through a translucent material because the material scatters light rather than absorbing it. Light enters the material and is scattered in different directions, allowing part of it to pass through. This diffusion of light throughout the material creates a semi-transparent effect.
