In my limited experience no. It's white to brown, dull in color, somewhat opaque.
cirrus
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
Cirrus clouds are made of tiny ice particles and appear white and feathery. They form at high altitudes and are often seen in fair weather, but can also indicate approaching weather changes.
Light is scattered when it hits the small dust particles. They appear to sparkle because sometimes the light is reflected toward your eyes.
Brine shrimp are small crustaceans that have a transparent body with segments, long antennae, and a pair of black eyes. They are typically less than 1 cm in size and have a curved tail that helps them swim in water. When they are still, they may appear as tiny, floating particles in water.
A solution is produced by dissolving a solid in a liquid and when completely dissolved there are no particles to be seen; just a transparent liquid (not if you put milk in your tea). A suspension is created when the tiny particles of a substance which is not dissolvable are stirred into a liquid. You can still tell that the particles are still there, and the liquid is not transparent. Think about the particles of cocoa powder stirred into hot water (without milk). You can find some of the powder left when you have drunk up.
tiny particles
The tiny white particles inside a pineapple are likely the fruit's seeds or remnants of the flower structures that produced them. Pineapples are generally propagated vegetatively, so they often contain undeveloped seeds that appear as small white specks. These particles are not harmful to eat and are a natural part of the pineapple's structure.
No because it is just a tiny crack. If the crack becomes bigger then it will have to worry already.
Not at all! Particles are tiny little things
These particles are called atoms.
Dust particles are tiny particles of solid material.
