Lesson: Light-Years Physics
In this lesson, we will learn how to describe the distances between different objects that make up the Milky Way and the Universe.
The speed of light is approximately m/s. There are approximately seconds in 1 year. Use these values to work out how far a beam of light will travel in 1 year. Give your answer in scientific notation to one decimal place.
There are meters in 1 light-year. What is m in light-years? Give your answer to the nearest light-year.
There are meters in 1 light-year. How many meters are there in 4 light-years? Give your answer in scientific notation to one decimal place.
