shock wave
Typically, when air is displaced by a pressure wave, it moves at the speed of sound. These pressure waves can be generated from one's vocal cords (when speaking), the vibration of an object, or the impact of one object against another. However, in certain cases, the pressure wave is generated by a collision between air parcels, such as when lightning heats the air immediately around it. This rapidly-expanding air crashes into the cooler air around it, generating a massive spike in pressure followed by a sharp drop-off. It is this sharp spike and drop-off combination that differentiates a sound wave and a shock wave. Shock waves can be either naturally generated, in the case of volcanic eruptions, lightning strikes, and asteroid impacts; however, they can also be generated through man-made means, such as explosives that derive their power either from chemical energy that is converted into thermal energy or by way of nuclear fission or fusion. If the pressure differential occurs in air where clouds can condense, the act of high pressure passing through the area and low pressure following can cause temporary "Wilson clouds" to form.
The Urban Dictionary Mug
Best mug i have ever purchased! Subscribe
I love it, but of course the definition Ichose for “Unicorn” is too long and gets cut off after “someone is remarkably attractive.” Is there any way to purchase a second mug that has the rest of the quote on it? They’d make a great set as a present. Please let me know. David Tillinghast dtilling480@gmail.com
