What is meant by light year is how far light travel in one?
It is the distance travelled by light in one year at a speed of 186,000 miles per second
What is the distance travelled by light in one day?
1 light day is a distance.
Is one meter the distance traveled by a ray of light in vacuum?
One meter is the distance travelled by light in vacuum in 1/299 792 458 second.
How many second in a light year?
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
Which is smallest 1AU 1 light-second a star or a planet?
Planet by a long way. They vary but in our solar system the largest is Jupiter and it's 66,854km across the middle. A light second is the distance travelled by light in a second = 299,792.5km A star can be lots of different sizes - our Sun is = 1,391,980km An AU is the distance from the Earth to the Sun = 149,598,000 km
How many normal years are there in one light year?
Only one. Because Light year is a messure of distance not of time. Light year is the distance travelled by light in one year.
What is the speed of a light year?
# The distance that light travels in a vacuum in one year, approximately 9.46 trillion (9.46 × 1012) kilometers or 5.88 trillion (5.88 × 1012) miles.
Why do scientists use light-year to show how far a star is from earth?
Light is the fastest thing we know...nothing is faster than light. So the distance travelled by light in 'some' time will be the greatest. And as the distances between stars etc is huge, Light Years are used as it is the distance travelled by light in a year. And nothing can travel more distance in one year. So light years are used.
Distance in meters that light travels in one second?
In a vacuum, light will travel 299,792,458 meters in one second.
Is a light year the distance traveled by light in one second?
No, that would be a light-second. A light year is the distance light travels in one year, which is 5,865,696,000,000 miles (5.87 trillion miles). Or 946,080,000,000,00 light travel 300,000 km per second
How do you get the distance light travels in one year?
1 light year equalls distance travelled by light in one year which equalls velocity of light * 1 year( 365.25 * 24(hour) * 60 * 60 ) which equalls value 9.467 * 10 power 15m.
How far is a lightsecond?
A light-second is the distance light travels in one second in a vacuum. That equates to 186,282.4 miles per second.
