If there is an unobstructed path, it can continue traveling practically forever.
Light travels approximately 299,792 kilometers in one second. This is equivalent to 299.792 megameters or 0.299792 gigameters per second.
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
Light travels at approximately 299,792 kilometers per second in a vacuum. To find out how many nanoseconds it takes light to travel 3.50 meters, we can use the formula: time = distance / speed. Converting 3.50 meters to kilometers gives 0.0035 kilometers, and then calculating the time gives about 11.6 nanoseconds. Thus, it takes light approximately 11.6 nanoseconds to travel 3.50 meters.
About 300,000 kilometers per second.
The speed of light is 186,282 miles per second.
The speed of light is equal to 299792.458 kilometres per second. There are 180 seconds in one minute. Therefore, in three minutes, light will travel 299792.458 x 180 = 53962642.44 kilometres in three minutes.
The distance from the Earth to the Sun is approximately 93 million miles (about 150 million kilometers). At the speed of light, it would take light 500 seconds to travel this distance. This is because light travels at a speed of about 186,282 miles per second or 299,792 kilometers per second.
Actually, the speed is 300,000 kilometers per second (one zero more than you put in the question). You can multiply that by 60 x 60 x 24, which is the number of seconds in a day.
less than a second if a mirror a second
One one year's time, light can travel 9.4605284 × 1012 kilometers.
