If the question is "What measures of distance are used with (visible) light?" Light is normally measured either in Angstroms, which are ten-billionths of a meter, or, more commonly today, in nanometers, which are one-billionths of a meter. Red light is around 700-690 nanometers (some claim all the way to 760 nm) and the wavelengths get shorter as the colors get "cooler" (that's psychologically cooler; they are actually getting more energetic). Around 400-390 nm they slip into the ultraviolet and we can no longer see them.

What colors of light reach the trees from the Sun?
The full spectrum of light reaches trees (and Earth). There are 7 (6 in some books) colors. They are red, orange, yellow, green, blue, indigo (debatable color), and purple.
How long for burst of light from sun to reach earth?
Once the light reaches the surface of the Sun, it takes approximately 8 minutes and 20 seconds to reach Earth. This can be calculated by dividing the distance to the Sun by the speed of light: 150,000,000 km / (300,000 km/second).
How do they time the time it takes for the light coming from the sun to reach the earth?
The distance to the Sun, and the speed of light, had been established separately, so the time was now easy to calculate.
Why is the light unable to reach the screen?
Explain why the light is unable to reach the screen
Is Capella is A light years away from earth how long will it take to reach earth?
A light-year is the distance light travels in a year. Therefore, if a certain star is "x" light-years from Earth, then it takes light "x" years to get fromthe star to us. Or the other way round.
Why is the distace between earth and the sun measured in light minutes and the distance between neptune and the sun measured in light hours?
Because it only takes 8 minutes for sunlight to reach Earth, but it takes 4 hours to reach Neptune.
Why is the distance from the sun and earth is measured by light minutes and the distance from the sun and Pluto is measured by light years?
There is nothing in our solar system far enough away from anything else in our solar system to be measured in light years. Light from the sun takes 340 minutes to reach Pluto, ie. 340 light minutes. Apart from the sun, the nearest star to us, Proxima Centauri, is 4.3 light years away.
If it takes 500 seconds for the light from the sun to reach the earth what is the distance to the sun in meters?
500 light seconds on my meter.
How many meters per second would it take stars light to reach earth?
Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
What colors of light reach the trees from the Sun?
The full spectrum of light reaches trees (and Earth). There are 7 (6 in some books) colors. They are red, orange, yellow, green, blue, indigo (debatable color), and purple.
How does light determine an objects's color?
Light determine an object's by the wavelength of light that reach to your eyes.light can reach your eyes after being reflected by an object,transmitted through an object,or emitted by an object.When your eyes receive the light,they send signals to your brain.Your brain interprets the signals as colors.
How long will it take for light to reach us from a galaxy 8 million light years away?
8 million years. A light-year is the distance light travels in a year.
How long would take light to travel from earth to mars at a distance of 56 million km?
At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.
How long does light from the sun take to reach mercury?
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.
What is The distance and travel time between Newcastle and sunshine?
Light takes about 8 minutes to reach earth
What stars are closest to us?
The closest star is the Sun. The distance is a little over 8 light-minutes. That is, it takes light from the Sun that long to reach us.The next-closest star is Proxima Centauri. The distance is about 4.2 light-years.
What colors do you mix to get a sand color?
Different sands are different colors. Usually sand if light, so you will have to use a lot of white. Slowly add brown to reach the color you want.
