It takes approx 194 seconds, or 3.23 minutes.
It takes light exactly one hour to travel in 1 hour.
At 1mph, 244 miles will take 244 hours to travel. At 60mph, 244 miles will take 4.0666... hours to travel. At the speed of light, 244 miles will take 1.31 milliseconds to travel.
Scientists use exponents to determine the speed of light, the distance between planets, or counting cells. Counting the number of cells can determine if someone does not have enough white blood cells, so they cannot fight diseases as easily. I know that people have million of cells in their body, so with exponents you do not have to write them all out, but in powers of ten.
Fringe width (for dark and bright bands): D * wavelength / d where, D = distance between screen and coherent sources (metres), wavelength = wavelength of light used is experiment (nanometres), d = distance between the 2 coherent sources (millimetres).
3000 miles (1609 meters/1 mile) = 4827000 meters Light travels at 2.998 X 10^8 m/s so 4827000 meters (1 s/2.998 X 10^8 m/s) = 0.016 seconds
Mercury's average distance from the sun is 36 million miles (58 million km).The time for light to cover that distance is about 193 seconds.
It really depends on the current distance of Mercury from The Sun. The orbit of Mercury (and of all the planets) is not perfectly circular. There are times Mercury is closer to The Sun than other times. When it's at its closest, or perihelion, Mercury is a little over 28.5 million miles from The Sun, and light takes just over 2 minutes and 33 seconds to travel from The Sun to Mercury. When Mercury is at is farthest distance, or aphelion, it is almost 43.4 million miles from the Sun, and light takes just over 3 minutes and 53 seconds to travel from The Sun to Mercury. So, based on the dates that Mercury is at aphelion and perihelion, your answer is: On August 21st, 2009, light takes 3 minutes and 53 seconds to travel from The Sun to Mercury On October 4th, 2009, light takes 2 minutes and 33 seconds to travel from The Sun to Mercury.
The distance light must travel is the distance from Sun to Earth - about 150 million km.
21 million light years is a distance of 1.23448496 × 10^20 miles. In other words, it would take a beam of light 21 million years to travel that distance.
Please note that a light-year is a measure of distance, not of time. A light-year is the distance that light travels in a year, and it is equivalent to about 9.5 x 1012 (that is, 9.5 million million) kilometers.
The Speed of light is approximately : 186000 miles per second The distance from the Earth to Mercury is approximately 48 million miles on average. so, 48000000 / 186000 = 258 seconds 60 seconds per minute so 258 / 60 = 4.3 minutes
At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.
Light will travel 5.6 million miles (9 million km) in 30 seconds. It doesn't matter where it's going.Pacing off that distance within the solar system, it's enough to get you about 15% of the way fromthe sun to Mercury, and about 11% of the way from earth to Mars when they are closest together.
Mercury's orbit is severely elliptical meaning that the planet's distance to How_far_is_Mercury_from_the_Sunvaries substantially.Closest: Mercury is 46 million kilometers (28.5 million miles or 0.31 AU) from the SunFurthest: Mercury is 70 million kilometers (43 million miles or 0.46 AU) from the Sun.Mean: Mercury is 58 million kilometers (36 million miles or 0.39 AU).
A minute is a measurement of time. A light minute is a measurement of distance. it's the distance light would travel in one minute. (That's about 10 million miles!)
20 million years, if you travel at the speed of light. For other speeds, use the formula: distance = speed x time. Solving for time, time = distance / speed.
it takes about 3-4 minutes for light to travel to mercury
