How many years are in a 100 light years?
Years are a measurement of time; light years are a measurement of distance. A light year is the distance light travels in one year (in a vacuum).
How was a light year discovered?
The light year was not discovered. It was made up, by people who kept coming up with distances like [ 25,866,280,000,000 miles ] in their work, and soon realized that they were going to need something bigger than a mile, so they invented the light-year.
Distance of one light year?
Light travels in a vacuum at 299,792,458 metres per second As there are 365.25 days in a year, each of 24 hours, each of 60 minutes, each of 60 seconds, there are 60 x 60 x 24 x 365.25 seconds in a year .... 31,557,600 .... this gets us into two HUGE numbers. A light year is officially defined as 9,460,730,472,580.8 kilometres or 9.461×1012 km
How was the length of a meter redefined in the year 1983?
On October 20, 1983, the meter was officially redefined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second.Light travels at 299792.458 km/sec, so the period was chosen as 0.00000000335641 second, or 3.35641 x 10-9 second.The original definitions (1799 and 1899) depended on a measured standard bar. In 1960, it was redefined as a relationship to the wavelength of light from ions of the element krypton. In 1980, the standard was based on the unusually cohesive wavelength of an iodine-stabilized helium-neon laser.
