Which is smallest 1AU 1 light-second a star or a planet?
A star would be smaller than 1AU, as 1AU is equivalent to the average distance between the Earth and the Sun. A planet would be smaller than 1 light-second, which is the distance light travels in one second.
What is the term for the distance light can travel in one year in a vacuum?
The distance light travels in one year is called a light year.It is approximately 6 trillion miles.9.4605284 x 1015 metresLight year is the distance traveled by light in one year. we just cannot imagine this. Because light travels 3*108 m/s. so just think how much it will travel in one minute, one day, one week, one month & one year.Exactly 9,460,730,472,580.8 (just under 9.46*1012) kilometers.
What does 6300 light years equal to in earth years?
A light year is a unit of distance, not time. It represents the distance that light travels in one year. So 6300 light years is the distance that light would travel in 6300 years on Earth.
Is a light year measured in distance?
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
What is the distance for a light-year?
A light-year is the distance that light travels in one year, which is about 5.88 trillion miles or 9.46 trillion kilometers. It is a unit of astronomical measurement used to describe vast distances in space.
What is the Distance travelled by light in one second?
300,000 km (186,000 mi)
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
How many normal years are there in one light year?
A light year is a measure of distance, not time, representing the distance that light travels in one year. Therefore, there is no concept of "normal years" within a light 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.
How many light years in a day?
A light year is a measure of distance, not time. A light year is the distance light travels in one year. In one day light travels 16,081,407,123 miles.
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.
When a person drives for several hours how does the distance traveled in one hour usually compare with the distance traveled in hours?
The distance travelled in one hour is usually less than that travelled in hours!
What is the concept of a light yea?
A light year is a unit of distance in astronomy that represents the distance light travels in one year. It is equivalent to about 5.88 trillion miles or 9.46 trillion kilometers. Light years are used to describe vast distances in space due to the immense speed of light.
Is one meter the distance traveled by a ray of light in vacuum?
Yes, one meter is defined as the distance traveled by light in a vacuum in precisely 1/299,792,458 seconds. This definition helps provide a precise and universal measurement for the meter.
What does a light year have to do with the sun and the earth?
A "light year" is a measure of distance, derived from "how far light can travel in one Earth year". Thus, if you shine a torch for the amount of time it takes the Earth to orbit the sun exactly once, that light would have travelled the distance of a "light year".
When a person drives for several hours how does the distance traveled in one hour usually compare with the distance traveled in other hours?
The distance travelled in any one hour is likely to be normally distributed with the mean equal to the mean distance travelled in the other hours and the standard error of this estimate will be the standard error of the distances travelled in the other hours.
