It is harder to measure the speed of light simply because it is so fast. The speed of light is 300,000,000m/s, where as the speed of sound is 340m/s. This means that the speed of light is almost 900,000x faster than that of sound.It is for this reason that you will see lightening before you hear it, and why you can use the lag time between the flash and boom to roughly estimate the distance of the lightning strike. For example, if lightening strikes 1km away from where you are standing, it would take about 3 seconds for the thunder to reach your ears (since the speed of sound is 340m/s, which is about 1km/s). The amount of time that it would take for the flash of lightening to reach your eyes is almost negligible: to travel 1km, it would only take light 0.000003s.
This would be the iris.
I recommend light brown hair...that would look amazing with blue eyes!But light blond would suit you very nice too!
Basically parallax, parallel axis, is the angle between two lines of sight. When you focus two eyes on something, your eyes are each looking slightly away from straight ahead. That is the parallax angle. So the farther away something is, the less the parallax angle. It is used in astronomy when a distant object is sighted and then sighted again half a year apart, we know that the earth has moved 2 AU in space, on the opposite side of the sun, and the angle from a fixed reference will provide a parallax angle which can then be used to relate the distance by trigonometry.
You can see stars that are light-years away. If you want to know the distance of the horizon, this will depend on the height of the spot where you are standing and your own height. There's a calculator at: http://newton.ex.ac.uk/research/qsystems/people/sque/physics/horizon/
Because even as light being very fast, at 30,000 feet in the air it takes the light longer to reach your eyes than it would if the jet was 30 feet away.
The light bounces off the object to get into our eyes. Actually there are many beams of light, but they don't all reach to your eyes.
It would be dark because X-ray light does not reach Earth's surface.
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.
It is determined by the wavelengths of light that reach your eyes.
it sees the color of an object or shine of light
Eyeglasses work by bending light rays in the eyes of those who can't see well so that they reach the back of the eye properly (called the retina). When the light rays reach the appropriate part of your eyes you see better.
the mirror can reflect anything
Technically, you can't "see" a black hole, since no light can escape from it, therefore the light cannot reach your eyes.
Well, I'm not so sure, but I think I know. Your eyes are in front of your ears, right? Well, light might reach your eyes first. Good Luck!
how do we see things?...There must be a light source that strikes or shines on the object and reflects and to reach your eyes..,
Yes it would dazzled but you would heart its eyes just don't shine things in there eyes.
