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

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

The speed of sound in glass at 29 degrees Celsius is approximately 4,850 meters per second.

When is speed of sound the greatest?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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?

User Avatar

Asked by Wiki User

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

Does the pressure of a gas affect the speed of sound?

User Avatar

Asked by Wiki User

The speed of sound in a gas does not depend on pressure.

See related links.


There are limits to the validity of this statement because it is valid for gasses that behave as "ideal" gasses. Thus, when near a pressure and temperature that is close to the point that the gas will condense into a liquid, this statement fails. For air, at all the temperatures which we experience, the speed of sound in air is independent of pressure.


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?

User Avatar

Asked by Wiki User

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.

How fast is the speed of sound at an elevation of 20000 feet?

User Avatar

Asked by Wiki User

Forget the altitude. Care about the temperature!

The speed of sound is dependent on the temperature and not on the air pressure of the altitude. At 20 degrees celsius or 68 degrees Fahrenheit the speed of sound is 343 m/s or 1236.3 km/h or 1126.7 ft/s or 667.1 knots.

Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".

Here is an easy calculator if you know the temperature. Do not care about the altitude!

Scroll down to related links and look at "Calculation of the Speed of sound in air and the important temperature".

Asume a temperature of -70 degrees Celsius for a height of 44,000 feet.

Does sound travel faster in cold air or hot air?

User Avatar

Asked by Wiki User

The speed of sound in air is given by the formula cair = 331.3 + (0.66 x T) m/s, where T is the temperature in °C. What that equation says is that the warmer air is, the faster sound waves travel in it. Wikipedia has particulars in a post on the speed of sound, and you've got a link to that article. Surf on over and check it out.

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

User Avatar

Asked by Wiki User

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

Why does sound travel further in water than air?

User Avatar

Asked by Wiki User

Well, water is a better conductor than air because the particles inwater have greater influence on each other than the particles in air, making the transmission of energy easier.

Water is better conductor than air because the molecules in water are closer together than the molecules in air.

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

User Avatar

Asked by Wiki User

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

Answer #2:

Many modern aircraft cruise at speeds greater than that of sound.

The adjective used to describe such travel is "supersonic".
