Question:-
What is the difference between year and light year ?
AnsWeR
Light:-
light or visible light electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye.
Light year:-
light year is the distance that light ravels in one year about 9.4707× 10 (12)Km.
Given ,
Riess (STScI/JHU)) A light-year is a measurement of distance and not time (as the name might suggest). A light-year is the distance a beam of light travels in a single Earth year, or 6 trillion miles (9.7 trillion kilometers). On the scale of the universe, measuring distances in miles or kilometers doesn't cut it
Light year is one of the unit of distance covered. It is basically defined as the distance covered by the light in one earth year. 1 light year = 9.461 trillion km.
A light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.88 trillion miles (9.5 trillion km).
