Speed of Light

Yes, lasers can work underwater. However, the effectiveness and range of the laser depend on factors such as water clarity, depth, and the type of laser used. Lasers can be used for various underwater applications such as communication, ranging, and imaging.

Nothing that has mass when it's stationary can move at the speed of light.

Electrons can move at any lesser speed.

In modern particle accelerators, they can be boosted to 0.99999c. But every additional ' 9 ' requires ten times as much energy as the previous one did.

No, red glass does not only reflect and transmit red light waves. It actually transmits the white light waves through the red glass creating a red glow. A transparent object generally transmits light while a solid object reflects light.

The Earth's north pole and south pole each rotate at the rate of [ 1 rotation / 2 pi radians /

360 degrees ] per 24hours 56minutes 4seconds.

Their linear speed, with respect to any other point on Earth, is zero.

The speed of light in a vacuum is constant at about 3 x 10^8 meters per second. The nature of the source of the light wave does not directly influence the speed of light in a vacuum. The speed of light is determined by physical constants in the vacuum, such as the permeability and permittivity of free space.

No, day and night have nothing to do with it. Light travels as far - and as fast - during the day than during the night.

In classical physics, negative speeds do not make sense as it implies going backward in space. In some contexts, negative speeds can be used in mathematical models or theoretical physics to represent certain relationships, but they do not have a physical interpretation as traveling at a negative speed.

Yes there is. Your shadow is the simplest evidence that light travels in straight line.

A solar eclipse is also evidence that light travels in straight lines, as is the fact that you cannot see around corners unless you use a mirror.

It depends on the specific gas, liquid, or solid, but in general the index of refraction is higher in solids or liquids than in gases. The speed of light is inversely proportional to the index of refraction.

Polarization.

That would depend on what time of year you left the Earth. But if you knew the distance between the two planets at their closest. Then all you have to do is divide that distance by 186,000 and this would give you how many seconds away Jupiter was from the Earth. The moon is 250,000 miles away that's 250,000/186,000 = 1.344 seconds away.

No known particles can travel faster than the speed of light in a vacuum, according to the theory of special relativity. In a medium like water, particles such as neutrinos can travel faster than the speed of light in that medium, but not in a vacuum. In solids, sound waves can propagate faster than light as well.

When an object is heated, its atoms become energized and move more rapidly. This causes the atoms to emit photons, which are packets of light energy. The higher the temperature of the object, the more photons are emitted, and the light produced may become visible to the human eye.

it slows down

Any time a wave enters a new median it is called refraction, the speed, direction, wavelength, and angle of the wave all change. This is why when you put your foot or a stick or something in water, it appears as if is bending. Also, refraction is represented by Snell's law which is n1/n2=sinx2/sinx1=v1v2 (x is usually expresses as theta).

The speed of light is exceeded by several things. Wave guides for instance. However all present theories preclude any information or mass to exceed the speed of light.

Neutrinos have never been sent through the CERN collider at super-luminal velocities.

The only general answer that's true in all cases is: Slower than in vacuum.

The exact speed depends on which gas, and the density of the gas, which

in turn depends on its temperature and pressure.

Like any other trip, that will depend on where you start out. If you're coming

from the sun, it'll take you roughly 81/3 minutes. From anywhere on Earth,

you can be there in 0.07 second or less, if you can handle the turns.

"Speed of light" is the correct term. Velocity refers to the speed of an object in a specific direction, while speed is the rate at which an object moves regardless of direction. The speed of light is approximately 299,792 kilometers per second in a vacuum.

Formerly, endoscope optics consisted of a series of thin converging "relay lenses", creating a succession of images in the air spaces between them. Following the innovation by Harold H Hopkins, the thin lenses in air were replaced by thin air lenses in glass. In other words, each lens consisted of a rod, with convex polished surfaces at each end. This increased the light throughput, and avoided the metal spacer rings needed in the old design. Some endoscopes instead use bundles of fiber optics to convey the image, which renders them flexible.

The speed of light in nanometers in scientific notation is 3*10 to the 17th power nanometers/second.

No. density is based on molecular mass. Air is considered a gas. Gases have lower densities than liquids at 'room temperature'.
