Question 1
The speed of light refers to the velocity at which light travels. It is the rate at which a
ray of light moves from the source to a particular target. On the other hand, the light-year
refers to the distance cover by fire in the space for one year. Many people would reason that
the speed of light and the light-year are the same things. However, the two elements are
different, but this has a close association (Williamson, Rector, & Lowenthal, 2019).
The speed of light is a compound measure that comes from the quotient of distance
and time. For one to attain the standard measure of the speed of light, the value of the length
and time must be taken. The fact that view is the fastest traveling element in the universe
makes it difficult to attain a specific speed. Therefore, the measured time is one year to check
the distance of 1 year in a vacuum. Thus, if the velocity of light is known, then the
parameters are broken to measure the distance covered by fire in other elements of the
universe.
Therefore, this relates to the time astronomers use I when traveling to space. Before
they move to the area, they must understand all the factors that are associated with light.
From this idea, the astronomers may find it easier ...
