Speed of Light

All of the frequencies emitted by the source would appear higher to me,

all of the wavelengths would appear shorter, and anything that was visible

to me would appear shifted toward the blue end of the spectrum, compared

to what it was when it left the source.

If, as you say, the source is approaching me at nearly the speed of light,

then the 'shift' will be extreme. What left the source as radio waves might

be visible to me, and what left the source as visible light might appear to me

as hard X-rays or even gamma rays.

By the way ... one thing that must be mentioned and appreciated is the fact that

even if the source is approaching me at nearly the speed of light, if I measure the

speed of the radiation from it as it sails past me, I'll see the radio, visible, X-ray,

whatever ... moving past me at the speed of light ... 300,000 kilometers per second.

Doesn't matter if the source is moving toward me, away from me, slow, fast, or sideways.

kilogram per second is the approximate speed of light

No, the speed of an object falling to the Earth increases due to the acceleration of gravity. At the beginning, the object has zero velocity and then accelerates until it reaches its terminal velocity, which is when the force of air resistance equals the force of gravity.

Yes, if you have a complete circuit, electricity will flow. A complete circuit includes a power source (such as a battery or generator), conductive path (such as wires), and a load (such as a light bulb or motor). When the circuit is closed, electrons will flow from the negative terminal of the power source through the conductive path to the positive terminal, creating an electrical current.

Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.

The speed of the light is 3.10^8 miles per second.what is the speed in miles per hour

It is 670,616,629 mph.

The pull of Gravity is instant - just there , no medium can influence it - to destroy it you have to distribute the mass , it takes time to get the masses together and takes time to take them away ! Gravity is not dependant on time ! Do some calcs yourselves on the supposed max. light speed of gravity and the effects on the alignment of the barycentres of binary masses (stars) !

Of course not,it is not true. The speed of light decreases

-- look up the electrostatic permittivity of free space

-- look up the magnetic permeability of free space

-- multiply them

-- take the square root of the product

-- take the reciprocal of the square root

The number you have is the speed of light in a vacuum.

In vacuum, the speed of light is a constant c = 300 000 000 m/s. In a transparent medium, light slows down by a factor of 1/n where n is called the refractive index of the medium. The refractive index of most common glasses is around 1.5 (3/2), so light will travel at a speed v = c/n = (2/3)c = 200 000 000 m/s in the glass.

no.

speed of light is always constant .

as long as the light stays in the same medium.

the speed is generally slightly different in different media.

no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower

The Greek word for speed is "ταχύτητα" (tah-HEE-tah).

Nothing is faster than the speed of light.

If you want to measure the speed of something, you first have to recall that

speed is (distance traveled) divided by (time to travel the distance), and then

you realize that you have to measure the distance it travels and the time it takes

to travel that distance.

If it happens to be the speed of light, then you immediately have a serious problem.

The speed of light is so great that ...

-- If you pick a distance that's easy to measure, then the time is impossibly short.

For example, if you pick ten miles, then you have to accurately measure 0.00005368

of one second, which is pretty tough.

-- If you pick a time that's easy to measure, then the distance is ridiculously long. For

example, if you pick 0.1 second, then you have to accurately measure 18,628.2 miles,

which is enormously tough.

Both of these methods are theoretically and technically perfect, and completely impossible

to actually use for the speed of light. You have to invent whole new clever ways to measure

speed.

The speed of light in the fibre is greater. As a result, light moving toward the outer covering is refracted back towards the core.

About 100,000 years. (the diameter of the Milky Way galaxy is 100,000 light years)

White light is simply a mix of red, green, and blue light. In a vacuum, all light travels at the speed of light (about 300,000 km per second), but it slows down a bit when passing through matter (glass, water, etc.).

no

299,792,458 meters (186,282 miles) per second.

plz answer :(

Yes, all forms of electromagnetic radiation, including gamma rays, X-rays, visible light, ultraviolet light, infrared light, microwaves, and radio waves, travel at the same speed in a vacuum, which is the speed of light.
