Light-second - Wikipedia

Web18 sep. 2012 · Light travels about 300,000 kilometers (or 186,000 miles) in one second. That means it goes about 30 centimeters — about one foot — in one nanosecond. In one femtosecond, light travels just 300 nanometers — about the size of the biggest particle that can pass through a HEPA filter, and just slightly larger than the smallest ... WebDistance = speed x time. time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s. What is light-year Class 8? A light-year is defined as the total distance travelled by light in one year. The speed of light is about 300,000 km per second. The distance covered by the light travelling at a speed of 300,000 km per second in a year gives one light-year.
