To show: One parsec equals 3.26 light years
Explanation of Solution
Introduction:
Light year is defined as the distance that is travelled in one year by the
Convert one year into seconds and find the distance travelled with a speed of light in one year.
Using time-distance relation,
Speed = distance / time
Therefore,
distance = (speed)(time)
here, speed is the speed of light and time is one year. Substitute these two values in above relation to get the distance. Therefore,
Using time-distance relation,
Speed = distance / time
Therefore,
distance = (speed)(time)
Here, speed is the speed of light and time is one year. Substitute these two values in above relation to get the distance. Therefore,
Also,
Conclusion:
Hence, one parsec equals 3.26 light year.
