A lightyear is a unit of length equal to the distance that light travels in 1 year. What is 1
lightyear expressed in units of meters? The speed of light is 3.00 × 100^8 m/s.
You want the distance traveled by light in one year.
distance = rate x time
distance = 3E8 m/s x # seconds in a year.
To find the distance in meters that light travels in 1 year, we need to multiply the speed of light by the number of seconds in a year.
First, let's find the number of seconds in a year. There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. Therefore, there are 60 x 60 x 24 = 86,400 seconds in a day.
Next, we need to determine the number of days in a year. A year consists of 365 days in the Gregorian calendar. So, there are 365 x 86,400 = 31,536,000 seconds in a year.
Finally, we can calculate the distance that light travels in 1 year by multiplying the speed of light by the number of seconds in a year:
Distance = Speed x Time
= 3.00 × 10^8 m/s x 31,536,000 s
Let's simplify the calculation:
Distance = 9.461 × 10^15 meters
Therefore, 1 lightyear is approximately equal to 9.461 × 10^15 meters.
