it is time
"Wavelength" is described in any convenient unit of length or distance, such as meter, foot, inch, furlong, kilometer, Angstrom, smoot, light-year, etc.
An example of a quantity of time is the second. Other examples are the minute and hour. You could go on and on - day, month, year, etc.
A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
the distance light travels in one year. light travels at around 300,000,000 metres per second. 1 year has 31,556,962 seconds in it, therefore a light-year is approximately 9,467,088,600,000,000 metres.
Well... yes, but it's not a very useful one. Light travels one light year in... one year. So the speed of light (which you cannot accelerate to) is about 1/8766 light years per hour.
Distance
how far u can travel at the speed of light in a year
No. A light year is a measure of distance. It is the distance light travels in a year.
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
Distance
Because that's how it is defined. A light-year is the distance that light travels in a year.
'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 year" is a unit of length or distance, equivalent to roughly 5,878,600,000,000 miles. (rounded)
A light year is not a physical object; rather, it is the distance light travels in a year.
A light year
A physical quantity measured in one dimension. Breadth, diameter, radius, depth, height, thickness, distance, displacement, diagonal, side all belong to length Meter is the unit for length in SI system of units For convenience we use mm, micrometer, nanometer, Angstrom, femtometer As larger units we use, kilo meter, astronomical distance, light year
-the quantity (magnitude,numerical value). -the units (in inch,meter,light year).
