Speed of Light

At a distance of 56 million kilometers, light requires 3.1 minutes to reach Mars from Earth.

When it is moving through a vacuum.

~33 Ohm

The Solar System (which includes Earth) is at a distance of about 27,000 light-years from the center of the Milky Way; since this distance won't change significantly over time, that means it will take about 27,000 years.

No!! Light beams of photons do not interfere with one another except in crystals as phonons.

bro, just do your physics homework

It varies greatly. It will depend on how far away it is from the object it's orbiting. If it is in a circular orbit around the Earth, its speed can be calculated by the formula:

speed = Squareroot(398600/(6371+altitude))

This will give you an answer in kilometers per second.

They are equal.

When the object is located at the 2F point, the image will also be located at the 2F point on the other side of the lens. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). The image dimensions are equal to the object dimensions. A six-foot tall person would have an image that is six feet tall; the absolute value of the magnification is exactly 1. Finally, the image is a real image. Light rays actually converge at the image location. As such, the image of the object could be projected upon a sheet of paper.

The speed of light is a constant in a vacuum and does not change, regardless of the medium it passes through.

given that the average distance distance from the Earth to the Moon is 382,500 KM

a Bike @ 10km per hour would take 4.3 Years

a Car @ 100km per hour would take 159.38 days

a ship @ 20,000km per hour would take 19.13 hours

@ the speed of light would take 1.28 seconds

THIS IS ALL WRONG

Linear magnification is the complicated process of how light travels and reflects. In a short answer, It would be the trajectory of the light and at what time and speed it traveled, followed by what route it took.

The speed of light is not medium: in vacuum, it is the highest speed that there can be. Hardly a definition of medium!

About 2/3 its speed in a vacuum.

In a rough, round figure? 930,000 to 1.

Sound travels roughly 1/5 of a mile per second in air.

Light travels 186,000 miles per second in a vacuum.

In five seconds sound travels one mile.

In five seconds, light travels 930,000 miles in a vacuum.

The speed of light, in vacuum, is exactly 299,792,458 metres per second or 299,792.458 kilometres per second. The values are exact because this is how a metre is defined.

The relationship between a kilometre and a mile is not exact, so it is not possible to give an exact figure for the speed in miles. It is approximately 186,282 miles per second.

Yes.

yes , if the light travel from less density to more density the speed will decrease

, the direction will change depend on the entered angle

None. At the speed of light, time stops completely. It is impossible for anything with an invariant mass to move at the speed of light; only particles with no "rest mass" (such as photons) can do so.

If both of them are in the same substance, then their speeds are equal.

Light travels at a constant speed of 299,792,458 meters per second in a vacuum. However, as light travels through different mediums, it slows down depending on the medium. The crazy thing about light though, is that if it leaves a medium and starts travelling back through a vacuum, it once again goes 299,792,458 meters per second.

The best fictional way to travel through space fast without messing with time is teleportation.

You have a faulty switch in the base of your indicator/light stalk. This switch wears out with use so the lights can flip easily to High beam from Low Beam. The fix: Replace the switch assembly and stalk.
