Abeam of light is traveling through a medium at 200,000 km/s. it enters a different medium and speeds up to almost 250,000 km/s. finally, it enters a third medium and halts. what were the media the light traveled through, in order? a. liquid, opaque solid, gas b. opaque solid, gas, liquid c. gas, liquid, opaque solid d. liquid, gas, opaque solid

This question concerns the general density of atoms in gasses, liquids, and solids.

Light cannot go through atoms. It can only go through the spaces in between the atoms.

Gasses do not have much density, as their atoms are freely flowing in space. Liquids are slightly more dense, as their atoms flow together. Solids are the most dense, as their atoms are tightly packed and do not generally move.

The beam of light passed through a medium at a normal speed. After passing through that medium, it sped up when going through another medium. When it hit a third medium, it stopped.

The first medium suggests a liquid. The second medium suggests a gas, because the beam speeds up and has a higher velocity than the medium before it. The third medium suggests an opaque solid, as the beam is stopped by this medium.

The answer is D. liquid, gas, opaque solid.

Hi Stkdazz,

Answer - d. liquid, gas, opaque solid

The reason its D, is because its says its going 200,000 km per hour then sppeeds up. The liquid is slower moving threw than gas because gas is just air. The halts and the only substance that can stop the beam of light is a solid.
