Answer:
Light waves slow down as they travel from gas to solid.
Explanation:
The speed of light is often quoted with reference to a vacuum. Light travels fastest in a vacuum and in a gas.
When light travels through other media such as solids or liquids, the speed of light is decreased due to absorption and scattering of photons by molecules as well as remissions.
Hence the speed of light decreases from gas to solid.

Hey there,
Your question states: <span>How long does it take for light from a star that is 8 light-years away to reach earth?
It take just about
(</span>
8 earth years) <span> for light from a star that is 8 light-years away to reach earth. That is how </span>

it would take.
Hope this helps.

Answer: The charges on cation and anion balances each other.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.




Thus
combines with two
ions to give neutral
