compressional waves
The rate at which water passes through any material is called percolation rate of water.
it bends and spreads out
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
The Colorado River passes through the Grand Canyon.
It will be like it was before
Transparent materials, such as glass or clear plastic, allow nearly all light to pass through them without significant reflection or absorption. This property makes them ideal for windows and lenses.
The material you are referring to is typically called a medium, such as air, water, or glass. As light passes through the medium, it interacts with the atoms or molecules in the material, causing it to scatter or refract, which can lead to the spreading out of light.
When light passes from air into water, it changes speed and direction due to the difference in refractive index between the two mediums. This causes the light to bend or refract, which can make objects appear distorted or shifted when viewed through the water. This effect is why objects underwater may appear closer or larger than they actually are when viewed from above the surface.
Light does not bend as it passes through a material. It bends when it passes from one material to another. This is called refraction. Light can also be dispersed, that is separated into its different colours, if it is refracted enough.

it is refraction

The phenomenon you are referring to is known as diffraction. When light waves encounter an obstacle or aperture, such as a narrow slit or edge, they diffract and spread out. This spreading out of light waves is a characteristic feature of wave behavior.
