Since we're within the "milky-way" you could say one second should do it.
To go all the way across it would take light 100,000 years (multiply by 365.25 x 24 x 60 x 60 to get seconds).
At the speed of light it takes 4 hours 11 minutes and 27 seconds.
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
It takes approximately 8 minutes and 20 seconds for sunlight to travel from the sun to the Earth at the speed of light.
The speed of light in a vacuum is the same, whether it goes to the Moon or elsewhere. By some theories, light travels at "c" relative to the local gravitational field. So if somewhere you found a gravitational field moving quickly, the light in that field might travel faster than the light in a different gravitational field. This is not -- not! -- standard physics. (yet).
Spacecraft can reach the Moon in a few days.Actually the time depends on the speed. You can assume an average speed, and use the formula: distance = speed x time Solving for time: time = distance / speed
distance = speed x time. Multiply the speed of light (in miles/second in this case) by the time in seconds, to get the distance travel in miles.
8 minutes 20 seconds at the speed of light. For any other speed, divide the distance (150 million kilometers) by the speed.
Having "A light-year is the distance light (speed = 2.998 108 m/s) travels in one year," you will then find how many seconds are in a year (31,556,926 seconds), multiply that number by 19 (given). Once you get how many seconds total in 19 years (599,581,594 seconds in 19 years) you will then multiple that number times the speed (2.998 108 m/s).Final Answer: 1.798 x 10172med
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.
Light is so fast that it is usually expressed as about 300,000 kilometers per second. If you multiply that by 3600 seconds / hour, you get the speed in kilometers per hour.
Frequency = speed/wavelengthPeriod = 1/frequency = wavelength/speed = (3,000,000)/(300,000,000) = 0.01 second
The speed of light is 2.997925 x 108m/s or 2.997925 x 105km/s
Since the speed of light, c, in vacuo is 186, 282.397 miles/sec and c is a universal constant, there is 1/c second per mile referenced to the speed of light.
Light seconds is a distance not a time.
At the speed of light it takes 4 hours 11 minutes and 27 seconds.
60.
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
