Speed of Light

No, you wouldn't be able to see the stars if you were traveling at the speed of light. Due to the effects of special relativity, time slows down as you approach the speed of light, causing everything outside your perspective to be distorted and appear different.

Ok its a bit hard and long, but its exactly 9460800000000 km for 1 light year.

The speed of light in air is approx 299,700,000 metres per second. This is not very different from its maximum speed which is its speed in vacuum: 299,792,458 metres per second. The fact that the beam emerges from water is irrelevant.

Two narrow slits with gap 0.03 mm and got separated by 3 mm will be illuminated by a monochromatic light which comes out of single slit. These two slits are named as Young's double slits. The waves coming out of these two will be in coherence.

There's no reason to expect that the intensity of light must

necessarily change when it enters a different medium.

Ultraviolet and visible light waves all travel at the same speed

whenever they're all traveling through the same material.

"Hypersonic" is a slippery, rubber, inexact word meaning faster than around

five times the speed of sound in the same medium, or, you might say, 'super

supersonic'.

If you define it, for a moment, as "exactly 5 times the speed of sound at sea level",

then the speed of light is only 174,806 times that fast.

Nothing is faster than the speed of light.

A spectrum.

White light is a mixture of different colors. Different materials have different surface properties; as a result, one material may reflect a larger percentage of red light, and a smaller percentage of other colors, such as blue or green light - thus, it will appear red. Another material may reflect more green light than other colors, so it will appear more green.

If the answer below doesn't solve the problem, have the alternator checked, as the regulator may not be working properly. Have it checked fairly soon, as fluctuations like those you describe can harm the car's computer and electronics. Clean both battery cables good and make sure there is a good ground between the engine and body. This ground is important so make sure it is tight and clean {no paint or grease}

A refracting telescope.

When light hits a two-way glass, part of the light is reflected back in the direction
it came from, while part of it goes one way, part of it goes the other way, and the
rest of it is absorbed by the glass and goes nowhere.

In any substance, all electromagnetic waves travel at the same speed

that light travels through that substance.

Any thin (low-pressure) sample of a gas with electric current flowing through it.

Ive seen it happen once on film and it happens very quickly the people inside the the pool remained where they were and the water flattened out in the yard very quickly.I think the odds of getting hurt are there but very slimm

Thank you. I guess it would depend if your yard goes downhill. I also saw a video where the water disappeared quickly, but the liner rolled down the yard. I shudder to think what would happen if the pool had a chain link fence around it. ???

A measurement of time can be made when an object moves back and forth in regular intervals, such as a pendulum. Essentially, motion is a measurement of time.

Units of time on the other hand include seconds, minutes, hours, as well as others such as Planck time and milliseconds.

It would not be possible to bend time even if you could manipulate gravity because gravity relies on the earths magnetic core, as gravity dose on any planet. If it were possible to manipulate gravity you could in theory change the mass of an object, but gravity has no effect on time. Time is something humans you to measure events and the duration between them. Time itself is not a thing, nor is it an event, in itself not measurable thus making time travel or the bending of time not possible.

As speed of light >> speed of sound, we can safely assume that the time taken for light to reach the observer is negligeable.

Taking speed of sound to be 340 ms-1 The distance can be found out by the formula

Distance = Speed * Time

= 340 * 3.4

= 1156 m

Wavelength is 720 nanometers.

Energy is 2.72 x 10-19 joules.

A shutter is a device that shuts. In a camera, it's the device that opens for a period

of time, usually very short, to allow light to pass through the aperture, and then shuts.

An aperture is an opening. In a camera, it's the opening in the camera's body, usually

where a lens and shutter are mounted, where the light enters on its way to whatever

is going to capture the image.

186,282 m/second

That is called the dielectric constant, also the square root of the relative permittivity.
