Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.

Interpretation Introduction
Interpretation:
The time required for the light to reach Earth from the Sun is to be calculated.
Concept introduction:
Dimensional analysis is a way to convert the units of measurement. In order to convert one unit to another, one needs to know the relationship between those units. These relationships are called conversion factors. Dimensional analysis is used to set up and solve a unit conversion problem using conversion factors.
Conversion factor is a fraction obtained from a relationship between the units. It is written as a ratio, and can be inverted to give two conversion factors for every relationship.
1 mi=1609.34 m, to convert mi to meter, the conversion factor is 1609.34 m1 mi.
1 min=60 s, to convert minute to second, the conversion factor is 60s1min.
The average speed of the International Space Station as it orbits the earth is 7710 m/s. What is this speed in mi/hr?
Molecular distances are given in nano-meters, where 1nm is equivalent to 1 x 10-9 meter. If the distance between carbon atoms in a diamond is 1.54 x 10-8 cm, what is this distance in nanometers?
