How fast is the shock waves travel?

Upvote5 Downvote2

Scientists have captured the blast from a supernova 10,000 light-years away in a cosmic speed trap, clocking the shockwave from the dead star's explosive end at speeds of nearly 8 miles per second.

Also to know is, what is a shock wave and how is it produced?

This phenomenon is known as a shock wave. Shock waves are also produced if the aircraft moves faster than the speed of sound. If a moving source of sound moves faster than sound, the source will always be ahead of the waves that it produces.

What is a sonic shock wave?

A sonic boom is the sound associated with the shock waves created whenever an object traveling through the air travels faster than the speed of sound.

What is a normal shock?

"Normal shocks" are a fundamental type of shock wave. The waves, which are perpendicular to the flow, are called "normal" shocks. Normal shocks only happen when the flow is supersonic.

How is a shock wave created?

This phenomenon is known as a shock wave. Shock waves are also produced if the aircraft moves faster than the speed of sound. If a moving source of sound moves faster than sound, the source will always be ahead of the waves that it produces.

How fast does a nuclear explosion?

The blast wind at sea level may exceed one thousand km/h, or ~300 m/s, approaching the speed of sound in air. The range for blast effects increases with the explosive yield of the weapon and also depends on the burst altitude.

How fast is the speed of an explosion?

And how fast you are. A C-4 explosion, for example, is virtually instant. Gases are released from the explosive at the super speedy rate of 26,400 feet per second (8,050 meters per second), pummeling everything in its immediate wake.

4

Is a sound wave a shock wave?

When a wave moves faster than the local speed of sound in a fluid, it is a shock wave. Like an ordinary wave, a shock wave carries energy and can propagate through a medium; however, it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium.

5

Is Shockwave safe?

Shockwave gets confused with Flash; they're related in a way but they're really two different things. In theory, like most software, Shockwave is safe as long as you keep it up to date. There are two tips that I have for keeping your computer safe while having Shockwave installed.

What is a normal shock?

"Normal shocks" are a fundamental type of shock wave. The waves, which are perpendicular to the flow, are called "normal" shocks. Normal shocks only happen when the flow is supersonic.

7

What is a shock wave therapy?

Extracorporeal shockwave therapy. Extracorporeal shockwave therapy (ESWT) is a treatment mostly used to treat kidney stones and in physical therapy and orthopedics.

8

How many miles would be affected by a nuclear bomb?

A 1 megaton nuclear bomb creates a firestorm that can cover 100 square miles. A 20 megaton blast's firestorm can cover nearly 2500 square miles. Hiroshima and Nagasaki were small cities, and by today's standards the bombs dropped on them were small bombs.

9

What is an oblique shock wave?

An oblique shock wave, unlike a normal shock, is inclined with respect to the incident upstream flow direction. It will occur when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses.

What is the use of Adobe Shockwave Player?

Adobe Shockwave Player (formerly Macromedia Shockwave Player) is a freeware software plug-in for viewing multimedia and video games in web pages, content created on the Adobe Shockwave platform. Content is developed with Adobe Director and published on the Internet.

How fast are nuclear weapons?

The giant TOPOL-M road-mobile intercontinental ballistic missile is one frightening creation of mankind. It can hide in cities, forests, or even nuclear-attack hardened bunkers. It'll travel at over 15,000 MPH while taking evasive action and pumping out decoys on the way to its target.

12

What is the fallout from a nuclear bomb?

Fallout is the radioactive particles that fall to earth as a result of a nuclear explosion. It consists of weapon debris, fission products, and, in the case of a ground burst, radiated soil.

13

What exactly is a sonic boom?

A sonic boom is a loud sound kind of like an explosion. It's caused by shock waves created by any object that travels through the air faster than the speed of sound. Sonic booms create huge amounts of sound energy. When an object moves through the air, it makes pressure waves in front of and behind it.

14

How long is a supernova last?

So, how long does a supernova take to explode? A few million years for the star to die, less than a quarter of a second for its core to collapse, a few hours for the shockwave to reach the surface of the star, a few months to brighten, and then just few years to fade away.

15

What is a shock wave in astronomy?

It is usually agreed that shocks caused by supernova remnants expanding in the interstellar medium accelerate the cosmic rays measured above the Earth's atmosphere. Shock waves in stellar environments, such as shocks inside a core collapse supernova explosion often become radiation mediated shocks.

16

What is a sonic boom and how is it created?

A sonic boom is the sound associated with the shock waves created whenever an object traveling through the air travels faster than the speed of sound. Sonic booms generate significant amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.

17

What is the wave drag?

In aeronautics, wave drag is a component of the aerodynamic drag on aircraft wings and fuselage, propeller blade tips and projectiles moving at transonic and supersonic speeds, due to the presence of shock waves. It is the sudden and dramatic rise of wave drag that leads to the concept of a sound barrier.

18

What kind of wave is a shock wave from an earthquake?

Shock waves. When an earthquake occurs, it produces shock, or seismic, waves. Two kinds of shock waves can travel through Earth's interior: P (primary) and S (secondary). These waves travel in different ways and at different speeds.

19

What is the critical Mach number?

In aerodynamics, the critical Mach number (Mcr or M* ) of an aircraft is the lowest Mach number at which the airflow over some point of the aircraft reaches the speed of sound, but does not exceed it. At the lower critical Mach number, airflow around the entire aircraft is subsonic.
