Water molecules scatter light because they are smaller than the wavelength of visible light. When light enters water, it interacts with the molecules, causing it to change direction and spread out in different directions. This scattering of light is what makes the water appear clear or transparent.
A solution with uniformly sized particles smaller than the wavelength of light will not scatter light.
In fog, the water droplets scatter the light in all directions. The beam appears straight because the individual water droplets scatter the light particles in a way that causes them to still travel in the same general direction as the original beam.
A solution that is completely transparent and has uniform refractive index throughout will not scatter light. This means that the particles in the solution do not cause light to deviate from its path as it passes through. Examples of such mixtures could be pure water or a clear oil.
The particles in the suspension will scatter the light, making the mixture appear cloudy or opaque. This is known as the Tyndall effect, where the dispersed particles reflect and scatter the light rays, causing them to be visible.

Any small slit will scatter light. Especially blue light.
Yes, colloids scatter light. Colloids are mechanical mixtures; all mechanical mixtures scatter light. Solutions are the only mixtures that do not scatter light. The scattering of light by mixtures is known as the Tyndall effect, btw.
Substances that do not settle or scatter light are typically transparent or translucent materials. These materials allow light to pass through them with minimal interference. Examples of such materials include clear glass, air, and water. When light passes through these substances, it does not scatter or settle; instead, it continues in a relatively straight path. This is in contrast to opaque materials, which absorb or reflect light, causing it to scatter or settle.
A solution with uniformly sized particles smaller than the wavelength of light will not scatter light.
water with food colouring is transparent. This is because in order to be translucent, the material must scatter the light waves, food colouring does not make a glass of water scatter incoming light waves, it simply makes them red :D
salt water is a solution, since it dose not scatter light, and appears as one layer.
In fog, the water droplets scatter the light in all directions. The beam appears straight because the individual water droplets scatter the light particles in a way that causes them to still travel in the same general direction as the original beam.

Particles in the atmosphere such as dust, water droplets, and gas molecules scatter sunlight, leading to phenomena like blue skies and colorful sunsets. Objects with irregular surfaces can also scatter light, causing glare or diffusing the light in different directions.
