What is the difference between shock wave and expansion wave?
Across a shock wave, the Mach number decreases, the static pressure increases, and there is a loss of total pressure because the process is irreversible. Through an expansion fan, the Mach number increases, the static pressure decreases and the total pressure remains constant.
What is the difference between a sound wave and a shock wave?
A sound wave is produced when energy in the form of disturbance propagates along the particles of the medium and it is carried along the medium due to the vibration of its particles. But a shock wave can only be produced when any object in air travels faster than the speed of sound.
What is shock describe the different types of shock wave?
One can imagine two types of shock waves: (positive) compression shocks which propagate into the direction where the density of the gas is a minimum, and (negative) rarefaction waves which propagate into the direction of maximum density.
What is shock waves in earthquake?
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). In addition to P- and S-waves, other types of seismic waves can travel along Earth’s surface. These are often the most destructive waves in an earthquake.
Are shock waves seismic waves?
When an earthquake occurs, it produces shock, or seismic, waves. Two kinds of shock wave can travel through Earth’s interior – P (primary) and S (secondary). These waves travel in different ways and at different speeds.
What is a shock wave quizlet?
What is a shock wave? A pressure wave that moves faster than the speed of sound.
What is another name for shock waves?

What is the difference between normal shock and oblique shock?
The Mach number and speed of the flow also decrease across a shock wave. If the shock wave is perpendicular to the flow direction, it is called a normal shock. When a shock wave is inclined to the flow direction it is called an oblique shock.
What are shock waves mention the characteristics of shock waves?
2.1 Characteristics of shock waves A shock wave has the following characteristics: It has an almost vertical front. The material jumps from the nonshocked to the shocked state instantaneously; that is, across a shock there is always an extremely rapid rise in pressure, temperature, and density of the shocked medium.
What type of wave is a shock wave?
shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.
What are the 3 types of earthquake waves?
There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface. A P wave is a sound wave traveling through rock.
