AnswersDriveIt 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.
People also ask, how a shock wave is formed?
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.

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.

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.

How fast is the shock waves travel?
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.

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 a sonic boom is formed?
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.

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.

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.
9
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.
10
What is a shockwave in an earthquake?
The shifting rock in an earthquake causes shock waves—called seismic waves—to spread through the rock in all directions. In a great earthquake shocks may be felt by people thousands of miles or kilometers away from the center.
11
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.
12
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.
13
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.
14
What is the definition of pressure wave?
Definition of pressure wave. : a wave (such as a sound wave) in which the propagated disturbance is a variation of pressure in a material medium — called also P-wave.
15
Are sonic booms legal?
Within the United States, it is illegal to break the sound barrier. Breaking the sound barrier leads to a sonic boom. And regulators have determined that people need to be protected from sonic booms. Planes produce sound waves when they travel.
16
What is the fastest aircraft in the world?
Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.
17
How fast is a fighter jet?
The aircraft can reach a maximum supersonic speed of Mach 2.35 (1,550 mph, or 2,500 km/h), which is 2.35 times the speed of sound. The Su-27 earned a reputation of being one of the most capable fighters of its time, and some remain in military use in Russia, Belarus and the Ukraine.
