It is the same speed all year. If you meant to ask: "How far does the speed of light go in a year?" The Answer is: about 6 trillion miles.
EDIT:
Light travels 9.454.254.955.488 kilometers per year which translates to 5.874.601.673.407 miles per year.
That's about 9.5 trillion kilometers or about 5.9 trillion miles.
This distance is called a light-year.
We don't know what "hour second" means, and have a nagging suspicion that it's quite meaningless. In vacuum, the speed of light is roughly -- 186,282 miles per second -- 670,615,200 miles per hour -- 16,094,764,800 miles per day -- 112,663,353,600 miles per week -- 5,878,715,206,000 miles per year.
The speed of light in a vacuum is approximately 670,616,629 miles per hour.
It is the distance travelled by light in one year at a speed of 186,000 miles per second
In vacuum, the speed of light is -- 299,792,458 meters per second -- 186,282.397 miles per second. If you were to travel at the speed of light, you could go around the Earth's equator approximately 7.6 times in one second. (Flying in a typical passenger jet, at a ground speed of 500 mph, it would take 4 hours to cross the continental US.)
The speed of light in a vacuum is 186,282.397 miles per second or 670,616,629.2 miles per hour.
The speed of the light is 3.10^8 miles per second.what is the speed in miles per hour
We don't know what "hour second" means, and have a nagging suspicion that it's quite meaningless. In vacuum, the speed of light is roughly -- 186,282 miles per second -- 670,615,200 miles per hour -- 16,094,764,800 miles per day -- 112,663,353,600 miles per week -- 5,878,715,206,000 miles per year.
The square of the speed of light is 89,880,000,000,000,000 meters2 per second2, or 34,700,000,000 miles2 per second2 "How fast" is meaningless, because the square of a speed isn't a speed any more.
The Speed of Light is 186,000 miles per second.
Speed of light in vacuum = 186,282 miles per second = 670,615,200 miles per hour
The speed of light in a vacuum is approximately 670,616,629 miles per hour.
The speed of light is 186,000 miles per second in a vacuum.
Hope speed is needed in miles per second. Its speed is 1,86,000 miles per second
It is the distance travelled by light in one year at a speed of 186,000 miles per second
A "Light Year" is a measure of distance. It equals approximately 9.5 trillion kilometers or 5.9 trillion miles. The Speed of Light (C) is: 299,792,458 meters per second 17,987,547,480 meters per minute 1,079,252,848,800 meters per hour 186,282 miles per second (~ 71/2 times around the Earth in one second) 11,176,920 miles per minute 670,615,200 miles per hour
In vacuum, the speed of light is -- 299,792,458 meters per second -- 186,282.397 miles per second. If you were to travel at the speed of light, you could go around the Earth's equator approximately 7.6 times in one second. (Flying in a typical passenger jet, at a ground speed of 500 mph, it would take 4 hours to cross the continental US.)
The sun's light has a speed of 186,000 miles per second.
