Medium-dense sand has a moderate compactness between loose and dense sands. It has a moderate level of porosity and offers a balance between drainage and water retention. This type of sand is commonly used in construction and landscaping for various applications.
When a wave moves from a dense medium to a less dense medium, most of the wave energy is reflected back into the dense medium, while a smaller portion is transmitted into the less dense medium.
Most of the wave energy is reflected back into the denser medium when a wave moves from a dense medium to a less dense medium.

The ray of light bends away from the normal when traveling from a less optically dense medium (medium A) to a more optically dense medium (medium B). Therefore, medium B is optically denser in this scenario.
When a wave passes from a less dense medium to a more dense medium, it generally slows down and changes direction. This change in speed and direction is called refraction. The wave may also experience a change in wavelength and frequency.

When light goes from a less dense to a more dense medium, it slows down and changes direction. This change in speed and direction is known as refraction. Refraction occurs because the speed of light is different in different mediums, causing the light waves to bend as they enter the more dense medium.
The answer depends on the grain size, lithology, moisture content, and level of compaction of the sand. Generally, one cubic ft of clean (no silt/clay), dry, fine to medium sand that has been compacted to a dense, non-yielding condition will weigh about 110 lbs., while a loose fine to medium sand will weigh about 100 lbs. per cubic foot.
In the compression part of a wave, the medium is more dense as the particles are packed closely together. In the rarefied area, the medium is less dense and the particles are further apart.
When a wave passes from a less dense medium to a more dense medium, its speed decreases while its frequency remains unchanged. Additionally, the wave may also experience refraction, causing it to change direction.
