Speed of Light

Photons behave more like a wave when they exhibit phenomena such as interference and diffraction, which are characteristics of wave behavior. This is evident in experiments like the double-slit experiment where photons create an interference pattern when passed through two slits.

According to Einestein's theory of general relativity, any massive body that causes an appreciable distortion in its surrounding space-time can bend light (e.g. large stars, black holes, etc.). Light that enters the event horizon of black holes are bent so much that it can never leave the black hole.

It isn't. The velocity of both is the same at about 2.998x108m/s. A change in wavelength is associated with a change in frequency not velocity. The frequency of Ultraviolet light is about 750 PHz (Peta Hertz) while that of infrared half that at 375PHz.

Light always travels at the speed of light.

The only time that's 299,792,458 meters per second is when the light is in vacuum.

It depends what angle it incidents on. For example: if the light was at right angles it wouldn't turn at all.

It is best to think of the mediums as two different road surfaces and the light as a car. As the light (car) comes from a dense medium (dirt) onto a rare medium (tar) it will go faster on the side that first touches the rare medium, and hence, turn it.

It would take approximately 40,238 years to travel 20 light years at 36,000 mph. This calculation takes into account the limitations of current space travel technology and the vast distances involved in interstellar travel.

If you need help with a specific physics lab, please provide the details of the experiment or problem you are working on. I can offer guidance on how to set up the experiment, analyze data, or interpret results.

Through a vacuum ... yes.

Through outer space, which is not quite a vacuum ... not quite, but very very close.

It is not possible for a particle with mass to reach the speed of light, as it would require infinite energy. Additionally, at speeds approaching the speed of light, relativistic effects become significant, causing time dilation and length contraction.

Assuming the incident ray enters the container at an angle, yes, but it would also bend if the container was straight. The phenomenon you're asking about is called refraction. The equation describing it is called Snell's Law: sin(θ1)/sin(θ2)=n2/n1 where θ1 and θ2 are the incident and refracted angles of the light ray and n1 and n2 are the first and second medium's "refractive index," which is a number that can be looked up. If the incident ray is perpendicular to the container's surface, θ1 is 0 and there is no bend.

The only significance of the container itself being curved is that when the light ray exits the plastic, it may not bend back to the direction it started out with.

The speed of light is approximately 299,792 kilometers per second. The number of lunar orbits required to cover this distance would be 12000 because the circumference of the Moon's orbit around the Earth is about 10,000 kilometers. Multiplying this by 12000 gives an approximate value close to the speed of light.

Light travels at a speed of approximately 299,792 kilometers per second (or about 186,282 miles per second) in a vacuum. This speed is commonly referred to as the speed of light, denoted as "c" in scientific equations.

Laser speed guns use a narrow beam of laser light to detect the speed of a moving vehicle by calculating the time it takes for the laser beam to travel to the vehicle and reflect back. The device measures the change in frequency of the reflected light to determine the speed of the vehicle based on the Doppler effect.

If by "light" you mean electromagnetic radiation, then you would call them energy radiators.

Doppler Shift......The wavelength of light emitted by a moving object is shifted. This effect is called the Doppler shift.

The question also reveals a poor understanding of 'moving'. Each object is it's own 'rest frame', and can only be moving with respect to something else specified, representing another rest frame.

For the purposes of real motion (and maximum speed c, including for the propagation of em waves) the reference is always the local background (frame).

(If you are timing a car go past at max speed v, then you accelerate to v', it does not mean the car can suddenly do v+v'!, so the speed is not with respect to anything except it's local background.)

The Special Theory of Relativity was valid for space that was empty (a perfect vacuum) and bodies that were perfectly rigid. We know know space is not empty and bodies are not rigid, but no other more valid or consistent theory has yet been adopted.

no, matter is not a form of energy a matter must exist in the either one of the three states of matter .

wait a minute that isn't what i was asking i was asking was energy a state of matter and plus your forgetting plasma that makes up almost the entire universe and stars. by the way plasma is an electrically charged gas!!

I don't believe there was any serious attempt to measure the speed of light before

Galileo. That was a couple of millennia after the golden age of the Greek philosopher

'scientists', who, I believe, assumed the transfer of light to be instantaneous, and the

perception of distant events to be simultaneous with the event.

It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration.

Also, the speed of light is a constant, which means it does not change.

No, sound waves and electromagnetic radiation do not travel at the same speed. Sound waves travel through a medium (such as air, water, or solid materials) at a speed that depends on the properties of the medium, while electromagnetic radiation (such as visible light, radio waves, and X-rays) travels at the speed of light in a vacuum, which is approximately 299,792 kilometers per second.

You can see a source of light because photons emitted from the source travel to your eyes, where they are absorbed by light-sensitive cells in the retina. This triggers nerve signals that are sent to your brain, which interprets the signals as visual information, allowing you to perceive the light source.

No, the Flash is a fictional character from DC Comics with superhuman speed that exceeds the speed of light. In reality, nothing can travel at or faster than the speed of light according to the laws of physics.
