What is the speed of light? Is it constant all over the universe?
A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s).
1. 4 light-seconds
2. 3 light-minutes
3. 2 light-days
4. 2 light-days, but this time answer in miles (enter just the number with no units)
Choose a unit distance in cm that would easily fit on a piece of paper. Let this be your scale distance, now divide your scale distance by 4.3 light years to get the scale that will allow you to convert between real distances and distances in your model. Scale = cm / 4.3 ly = cm / ly
