Why is the speed of light 186000 miles per sec?

That's just the way it works out. _________________ In cases like this, the question "why" isn't the best question. It is interesting to note that the speed you mention is the speed of light in a vacuum. And although light doesn't need a medium through which to travel, it can be slowed down depending on what it's traveling through. If projected through a Bose-Einstein condensate, it can be slowed to the point of something on the order of tens or hundreds of meters per second. But the most amazing thing is that in a vacuum, any observer from any point of view, in any frame of reference, will observe the light and clock it at 186000 miles per second, another reason why 'why' becomes literally unanswerable. This is a personal thought and not based on any research that I know of. I think that light travels at c, and c is also the velocity of time itself. If we could accelerate to c, we would reach a point where time is not passing for us; we would be motionless in relation to time. As we decelerate, we begin to move relative to time and we experience time passing. Or perhaps, somehow, we are the ones moving at c, giving us the experience of time passing (because we are passing through it), and what we cannot do is 'slow down to a stop' by accelerating in the other direction.

What is the speed of sound?

The speed of sound is the velocity of sound through a mechanical (elastic) medium (such as air, water, concrete, etc.). It will vary as the medium through which it travels varies. In general, the speed of sound is faster in liquids and even faster in solids.

In air, the speed of sound has little to do with the atmospheric pressure "at sea level" or with the humidity, but the temperature is very important. Therefore we can set aside questions of altitude and humidity.

The speed of sound in air is 343 m/s or 1126.547 ft/s (768.095 mph) at a temperature of 20°C or 68°F

The air pressure and the air density are proportional to each other at the same temperature.

Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure" and "Calculation of the speed of sound".


The speed of sound at sea level is equal to 340.29 metres per second.

343 meters/second (1,125 ft/s) or 1,236 kilometers/hour (768 mph).

This speed is variable, dependent on the air density (elevation), temperature, and humidity.

Notice: The speed of sound changes with temperature and

a little bit with humidity − but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading.

The temperature indication, however, is absolutely necessary.

The speed of sound at 20 degrees Celsius (68 degrees Fahrenheit) is 343 meters per second.

Speed of sound is 331m/s in Air Medium. It varies from medium to medium. It is highest in some crystals.
340.29 m / s
speed of sound at sea level = 340.29 m/s

It is hard to be too precise as the speed of sound is affected by humidity. Over land the speed of sound is 331.3 m/s but slightly higher when the air is wet. Generally, the difference in seconds between the lightning and the sound of thunder is divided by 3 to get the distance of the lightning strike in kilometres.

What would cause a grinding sound when accelerating straight and a loud whirring at all speeds with the engine temperature a little higher than normal?

The grinding sound when accelerating could indicate a worn-out CV joint or a problem with the transmission. The loud whirring noise at all speeds could be due to a failing wheel bearing or an issue with the differential. The higher engine temperature than normal could suggest a problem with the cooling system, such as a failing water pump or a blockage in the radiator.

What could a rotation sound that increases with speed coming from behind the dash of A '96 dodge ram 1500 be?

It could be a failing speed odmeter cable. remomove the cable from the transmission and see if the noise stops.

How do I increase the sound of my blinker at my 1999 Lexus LS 400?

If you are asking for the location of the Turn Signal Flasher Relay, it is located in Junction Block 1A (under dash on drivers side). Block 1B has the fuses, Block 1A the relays. The flasher is the small relay at the end opposite the group of four (4) relays.

What does sound go faster through a vacuum or a solid?

Sound travels faster through a solid than through a vacuum. In a solid, sound waves propagate through the material's molecules, leading to faster transmission. In a vacuum, there are no molecules to transmit sound, so it cannot travel at all.

Why is Katherine so quiet?

There could be various reasons why Katherine is quiet. She might be shy, introspective, or simply prefer to listen rather than talk. It's important to respect her personality and allow her to open up in her own time.

Would you die instantly if you got slashed by a sword at the speed of sound?

No, you would not die instantly from being slashed by a sword at the speed of sound. The more important factor affecting potential lethality would be the severity and location of the injury, rather than just the speed of the sword. Any injury caused by a sword moving at the speed of sound would be extremely severe and likely fatal, but death would not be instant.

What strange thing happens to this plane in faster-than-sound flight?

In faster-than-sound flight, a plane can experience a shockwave known as a sonic boom. This is caused when the plane reaches and exceeds the speed of sound, resulting in a sudden, loud noise like a thunderclap. It is a strange phenomenon that can be disruptive and alarming for those on the ground.

What is the frequency of 220 Hz and a wavelength of 3 meters?

The frequency of 220 Hz with a wavelength of 3 meters can be calculated using the formula v = fλ, where v is the velocity of the wave. Assuming the velocity is the speed of sound in air (343 m/s), we can rearrange the equation to solve for frequency: f = v/λ = 343/3 = 114.33 Hz. Therefore, the frequency is approximately 114.33 Hz.

What is the speed of sound in glass at 29 degree Celsius?

Speed of sound in air is c ≈ 331 + 0.6 × T.

T = Temperature.

Speed of sound in air at 29 °C is c ≈ 331 + 0.6 × 29 = 348.4 m/s.

When is speed of sound the greatest?

The speed of sound is greatest in solids, as the particles are closer together and can transmit vibrations faster. In general, the speed of sound increases with an increase in density and elasticity of the medium.

What happens to the sound an object makes when the speed of vibrations decreases?

When the speed of vibrations decreases, the pitch of the sound produced by the object lowers. This is because the frequency of the vibrations decreases as well. As a result, the sound becomes deeper or lower in tone.

How fast was chuck yeager going when he broke the sound barrier?

After becoming a Fighter Ace in World War II; Chuck Yeager was a test pilot and flew the Bell XS-1 which was built to try to fly faster than the speed of sound.

The Bell XS-1 had what was referred to as a "flying tail" so that the shock wave (caused by flying in the trans sonic region), which formed on the hinge of the horizontal stabilizer, would not disable the controls.

Who was the first pilot to fly an airplane faster than the speed of sound?

Captain (later colonel) Charles "Chuck" Yeager flew the Bell X-1 faster than the speed of sound to become the first pilot to do so. "Glamerous Glennis" rocketed past the sound barrier on 14 October, 1947. ANSWER 2 actually several pilots during world war 2 broke the sound barrier in mustangs and ligtnings and possible other high performance fighters when they went into a dive at full speed - unfortunetly those planes were not designed to do so and broke up so noone survived Chuck Yeager

Who first broke the sound of speed?

Chuck Yeager..

I don't think anyone has yet to break the speed of sound on the ground, I could be wrong, anyone?

Why doesn't the Doppler shift appear when an observer moves toward the source?

Doppler's effect does not happen when the observer is moving towards the source because unlike the source when observer moves forward the waves are not compressed and they pass the observer without being compressed and since the doppler effect is due to the Change in wavelength of the wave, it fails to occur.

What is the speed of light and sound in mph?

Speed of light (in vacuum)= approx 671,000,000 mph.Speed of sound (in air at sea level) = approx 760 mph.

Is the speed of sound in cork greater than speed of sound in water?

No. The denser the material, the faster sound moves through it.

What was the date when the plane flew faster than the speed of sound?

The Bell X-1 rocket plane first exceeded the speed of sound on 19 January 1946. The piolet reported big problems with serious shaking of the aircraft that we now understand to be as a result of the sonic boom

How will you find the speed of sound in air?

Hello by doing Resonance Column experiment, Kundt's tube and Quinkes tube experiment.

Which two factors sound intensity?

Reverberation time, loudness, Focusing, interference, echo, echelon effect, resonance, noise

Velocity of the sound is maximum in which gas?

That is a difficult question. I would say that the denser the gas, the faster the speed of sound. Since the gas occupies a lot more space, sound energy/waves are transmitted more easily. :D
