How Come Light Travels Faster Than Sound Through Air? - Fixanswer

Ergo, light is made of electromagnetic waves and it travels at that speed,

because that is exactly how quickly waves of electricity and magnetism travel through space

.

Why does sound travel slowest in air?

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because

the molecules of a gas are farthest apart

.

What is quicker than the speed of light?

Albert Einstein's special theory of relativity famously dictates that

no known object can travel faster than the speed of light in vacuum

, which is 299,792 km/s.

Is there anything faster than the speed of light?

A reference frame with zero width and with no progression in time is really a reference frame that does not exist. Therefore, this tells us that

nothing can ever go faster than the speed of light

, for the simple reason that space and time do not actually exist beyond this point.

Is lightning faster than the speed of light?

While the flashes we see as a result of a lightning strike travel at the speed of light (670,000,000 mph)

an actual lightning strike travels at a comparatively gentle 270,000 mph

.

Is lightning slower than sound?

Lightning travels at the speed of light, about 186,000 miles per second. This means that you see lightning pretty much when it happens. When lightning strikes, a noise is made which we call thunder.

Thunder travels much slower, at the speed of sound, about 1088 feet per second.

When did the sound travel fastest slowest?

The speed of sound depends on the medium in which it is transported. Sound travels

fastest through solids, slower through liquids and slowest through gases

.

Who discovered the speed of light?

Part of the Cosmic Horizons Curriculum Collection. In 1676, the Danish astronomer

Ole Roemer

(1644–1710) became the first person to measure the speed of light. Roemer measured the speed of light by timing eclipses of Jupiter's moon Io.

Is Lightspeed travel possible?

Based on our current understanding of physics and the limits of the natural world,

the answer, sadly, is no

. According to Albert Einstein's theory of special relativity, summarized by the famous equation E=mc
²
, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.

What if the speed of light was infinite?

If the speed of light was infinite,

all points in the universe would be able to communicate with each other instantaneously

. We wouldn't be able to tell which stars are further away or older etc. Our universe would be one instantaneous here and now. No past, no present and no future.

Where does sound travel fastest?

Sound waves can only travel through a solid, liquid or gas medium. They travel fastest

in solids

, then liquids and slowest in gases.

How much faster does light travel than sound?

The speed of light is

much faster than the speed of sound in air

. If you want to compare, the speed of sound in air is ~ 343 m/s and the speed of light is 3×10
¹⁰
m/s. In other words, light travels 186 thousand miles in 1 second, while sound takes almost 5 seconds to travel 1 mile.

How do sound travels through air?

Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as air, water and wood.

When an object vibrates, it causes movement in the particles of the medium

. This movement is called sound waves, and it keeps going until the particles run out of energy.

Is light faster than darkness?

Darkness travels at the speed of light

. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.

Is a black hole faster than light?

To escape from within a black hole requires faster than light speeds

, but according to Einstein's theory of gravity, General Relativity, gravity is the distortion of space and time caused by the presence of mass.

Is time travelling possible?

In Summary:

Yes, time travel is indeed a real thing

. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

Is superluminal travel possible?

If humanity ever wants to travel easily between stars, people will need to go faster than light. But so far,

faster-than-light travel is possible only in science fiction

. In Isaac Asimov's Foundation series, humanity can travel from planet to planet, star to star or across the universe using jump drives.

Are Tachyons real?

A tachyon (/ˈtækiɒn/) or tachyonic particle is a hypothetical particle that always travels faster than light.

Physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics

.

Is the universe expanding faster than light?

The quick answer is

yes, the Universe appears to be expanding faster than the speed of light

. By which we mean that if we measure how quickly the most distant galaxies appear to be moving away from us, that recession velocity exceeds the speed of light.

What is the fastest thing in the universe?

Light

travels about 186,270 miles (more than seven times the circumference of Earth) in one second. In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.

Is lightning hotter than the sun?

In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (

5 times hotter than the surface of the sun

). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.

Who proved that Tachyon is faster than light?

George Sudarshan	Alma mater CMS College Kottayam Madras Christian College University of Madras University of Rochester	Known for Coherent states Optical equivalence theorem Glauber–Sudarshan representation GKSL equation V-A theory Tachyon Quantum Zeno effect Open quantum system Spin–statistics theorem

Is lightning faster than a bullet?

That is

faster than a bullet fired from an assault rifle- 1000 metres per second

. A natural disaster poses serious risks to your life, liberty and limb.

Which is first thunder or lightning?

If we are watching the sky,

we see the lightning before we hear the thunder

. That is because light travels much faster than sound waves. We can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder.

Does bullet travel faster than sound?

When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That's equivalent to over 1,800 miles per hour. To put that in perspective, it's amazing to realize that

bullets travel over twice the speed of sound

!
