###### Asked in Science, Speed of Light

### Is there a formula for working out the speed of light?

Answer: The speed of light was determined through
experimentation, such as the timing of moons passing behind
Jupiter. Many formulas are based upon the speed of light, but that
number had to be determined beforehand.
Light travels 299,792,458 meters per second (or 186,282.397
miles per second in a vacuum.
Answer: Yes, the speed of light can be deduced from the
electrical properties of empty space. However, in practice it is
more accurate to measure the speed of light.

### What value must you know to calculate how much a light-year represents?

A "light year" is the distance that light travels in one year.
Light travels so fast that the speed of light is measured in miles
per second or km per second.
You probably already know how many seconds are in a minute (60),
how many minutes are in an hour (60), how many hours are in a day
(24), and how many days are in a year (365.24). So if you knew the
speed of light, you could multiply all those...

### What is the speed of light energy in solids?

The answer depends on the solid.In glass (pyrex) it is approx
204,000,000 metres per second.
In heavy flint glass its speed falls to 156,000,000 metres per
second.
In diamond it is 124,000,000 metres per second.
In lead, for example, it is 115,000,000 metres per second but it
does not travel very far before it is stopped through
absorption.
Also, in some crystals the speed of light depends on the
direction of travel.
