-- The distance that light travels in some amount of time is expressed in units of distance.
-- The time that it takes light to cover some amount of distance is expressed in units of time.
-- The speed of light is expressed in units of speed . . . distance/time
Not really. A light year is a measure of distance. It is the distance light can travel in one earth year, about 6 trillion miles
False the light year is not a unit of time it is a unit of distance true.
Distance (metres) = velocity (metres / sec) * time (seconds) > velocity of light = 299 792 458 metres per second 1 year = 365.2425 days = 31 556 952 seconds > Distance = 9 460 536 207 068 020 metres Distance = 9.46054 * 1015 metres approx.
A light year is a measure of distance not time. A light year is the distance light travels in one year. So for light to travel 6,300 light years, would take 6,300 years
A light-year is a unit of distance, not a unit of time.

A light year is a unit of distance, not a physical quantity. It represents the distance that light travels in one year in a vacuum.
Stars are not measured in light years. The distance between them is.

Distance
Because that's how it is defined. A light-year is the distance that light travels in a year.
No. A light year is a measure of distance. It is the distance light travels in a year.
The speed of light can be measured using a microwave by sending a microwave signal from one point to another and measuring the time it takes for the signal to travel. By knowing the distance between the two points and the time it takes for the signal to travel, the speed of light can be calculated using the formula speed distance/time.
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
light years.
Wavelength
Speed is measured by calculating the distance you have gone and how long it took you to get there. speed = distance over time
