Is speed of light faster than sound?

Light is faster than sound . Because light doesn't need a medium to travel . The speed of sound through air is about 340 meters per second. It's faster through water and its even faster , through steel .

Subsequently, one may also ask, is speed of light or sound faster?

The speed of light is much faster than the speed of sound. Sound moves at 343 metres per second (thats about 770 miles per hour!) The speed of light is a little trickier. In a vacuum it is roughly 300 000 000 metres per second (so nearly 900 000 times faster than sound!)

Likewise, is Sonic faster than the speed of light? sonic is faster than light. meaning sonic can go 7.29 times faster than light in sonic unleashed. even in the Japanese manual, it states “sonic can go anywhere at light speed.” sonic is even confirmed faster than light and the fastest video game character of all time. he can further increase his speed to 3000.

Also know, how fast is the sound of speed?

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

Is anything faster than light?

There is no limit to how fast the universe can expand, says physicist Charles Bennett of Johns Hopkins University. Einstein's theory that nothing can travel faster than the speed of light in a vacuum still holds true, because space itself is stretching, and space is nothing.

Can light travel forever?

Nope! Light is a self-perpetuating electromagnetic wave; the strength of the wave can get weaker with the distance it travels, but as long as nothing absorbs it, it will keep on propagating forever.

Why does time stop at the speed of light?

Just like its time slows down when an object moves at a high speed, the same object will also get shorter in its direction of motion. At the speed of light, time stops and the object will shrink to zero length.

Is light speed possible?

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. Early scientists, unable to perceive light's motion, thought it must travel instantaneously.

What is the fastest thing in the universe?

Within the universe, light is the fastest things, light as no mass, things with no mass could reach light speed. A shadow is the next thing, which can travel faster than light.

What comes first light or sound?

As with all the other answers lightning do in fact come first, but the speed of sound and light is not the only answer. Yes light is quicker than sound so we do see the lightning strike first, but the two does not in fact occur at the same time. The first thing that happens is the step leader is created.

What does speed of sound depend on?

The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

How fast is a bullet?

The average bullet travels at 2,500 feet per second (around 1,700 mph). If you reacted to the sound of the gun going off and required 0.20 seconds (twice that of the fastest Olympic sprinters) to react, then you would need to be at least 500 feet away to successfully dodge a bullet.

How fast is the speed of dark?

This mysterious energy makes up 80 percent of all matter in the universe. In a 2013 study, scientists determined that dark matter should have a speed of 54 meters per second, or 177 feet -- slow compared to the speed of light [source: Armendariz-Picon and Neelakanta].

How loud is a sonic boom?

Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. When an aircraft is near the sound barrier, an unusual cloud sometimes forms in its wake.

Why is speed of sound so slow?

Sound is slowed down by the necessity of carrying all that bulk along with it. Even in a rigid material, like a steel rod, sound is slowed down by the need to carry the energy from one atom to the next, and atoms are always going to move far slower than the speed of light.

What is the fastest jet?

Lockheed SR-71 Blackbird

How fast is the speed of sound in water?

Sound waves tend to travel faster at higher temperatures. I have found different values for the speed of sound in water in different sources. They range from 1450 to 1498 meters per second in distilled water and 1531 m/s in sea water at room temperatures (20 to 25 °C).

What is sonic velocity?

Simply stated, sonic velocity is the velocity of sound in that fluid (a gas/vapor). It is a maximum that can be achieved by the fluid. As you know, flow is induced due to a pressure difference between the upstream condition and the downstream condition.

How fast is subsonic?

Subsonic ammunition is ammunition designed to operate at speeds below the speed of sound, which at standard conditions is 343.2 m/s (1,126 ft/s). This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot.

What is Sonic's max speed?

When you do the math, Sonic's top speed turns out to be about 10 meters per second. The speed of sound? That's 340 meters per second.

Who is the fastest Sonic Character?

3 Tails Miles "Tails" Prower is a fictional character in Sega's Sonic the Hedgehog series, and the title character's best friend and sidekick. Yes, Sonic is faster than him, but he is faster than Knuckles. Therefore, he flys somewhere between 770 and 400 mph.

What is Flash's top speed?

As of The Flash's (2014 - ) March 22, 2016 episode “Trajectory,” The Flash's (Grant Gustin) top speed is Mach 3.3 or 2,532 miles per hour, making him comfortably faster than the fastest jet a human has ever piloted (the current air speed record is Mach 2.8), but also far slower than the speed of a space shuttle (whose
