The primary reason for this is that the sound shock wave modifies as it passes through the atmosphere. Sound travels roughly 750 mph (1,200 km/h), or approximately one mile every 5 seconds (one kilometer every 3 seconds).
How long does sound take to travel 1 mile?
Thunder travels much slower, at the speed of sound, about 1088 feet per second. It takes sound about 5 seconds to travel one mile.
Does sound travel at 1 mile a second?
In air at a temperature of 70° F (22.2° C), sound travels at a speed of about 1,129 feet (344 meters) per second, which is roughly equivalent to one-fifth of a mile in one second , or one mile in five seconds (or one kilometer in about three seconds).
How does Shockwave calculate distance?
...you can measure the time between the flash and the shockwave to get a rough estimate . The shockwave travels about about 1km in 3 seconds or 1 mile in 5 seconds, so e.g. the tent was about 2 km away, since the gap was 6 seconds.
How far can a blast wave travel?
Within a 6-km (3.7-mile) radius of a 1-megaton bomb , blast waves would produce 180 metric tons of force on the walls of all two-story buildings, and wind speeds of 255 km/h (158 mph). In a 1-km (0.6-mile) radius, the peak pressure is four times that amount, and wind speeds can reach 756 km/h (470 mph).
Is shock wave lithotripsy painful?
Shock wave lithotripsy is a safe treatment to get rid of kidney stones. Passing even tiny kidney stone fragments can hurt — sometimes a lot . If you have shock wave lithotripsy, expect to feel some discomfort as stone fragments pass in the days and weeks after treatment.
How fast is a light year in mph?
In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).
Whats faster sound or lightning?
Lightning and thunder happen at the same time. But you see lightning before you hear thunder because light, which travels a million times faster than sound , arrives almost instantly. Sound, on the other hand, takes about five seconds to travel one mile.
How long is a mile?
mile, any of various units of distance, such as the statute mile of 5,280 feet (1.609 km). It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet. About the year 1500 the “old London” mile was defined as eight furlongs.
How far can sound travel in 7 seconds?
As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.
How fast can we travel compared to the speed of light?
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
How long does it take for sound to travel 3 miles?
The speed of sound changes depending on temperature and humidity but one can estimate that sound travels 1 mile in roughly 5 seconds .
What is the difference between a blast wave and a shock wave?
A blast wave travels faster than the speed of sound and the passage of the shock wave usually lasts only a few milliseconds .
What is a normal shock wave?
A normal shock wave is a shock with the wave front normal to the freestream flow . • Normal shocks occur, for example, in supersonic internal and jet flows. • Studying a normal shock is the first step in gaining an understanding of shock waves.
Who invented shock waves?
In the USA the first patent of an electrohydraulic shock wave generator was accepted ( Frank Rieber , New York, Patent No. 2.559. 277). End of the 50’ies the physical properties of electromagnetic generated shock waves have been described.
How far does a shockwave from a nuke travel?
This damage may correspond to a distance of about 3 miles (4.8 km) from ground zero for a 10 KT nuclear explosion . The damage in this area will be highly variable as shock waves rebound multiple times off of buildings, the terrain, and even the atmosphere.
How fast do Explosions travel?
Gas explosions can either deflagrate or detonate based on confinement; detonation velocities are generally around 1600 m/s to 1800 m/s but can be as high as 3000 m/s . Solid explosives often have detonation velocities ranging beyond 4000 m/s to 10300 m/s. Detonation velocity can be measured by the Dautriche method.
How far away from a nuke is safe?
Heat is the prime concern for those closer to a nuclear blast, with people up to 6.8 miles away suffering first-degree burns and third-degree burns hitting anyone up to 5 miles away. You’ve got to consider the immense thermal radiation too, which travels at the speed of light.
How long does it take to recover from shock wave lithotripsy?
The recovery time is usually fairly brief. After treatment, the patient can get up to walk almost at once, Many people can fully resume daily activities within one to two days . Special diets are not required, but drinking plenty of water helps the stone fragments pass. For several weeks, you may pass stone fragments.
How successful is extracorporeal shock wave lithotripsy?
How successful is extracorporeal shock wave lithotripsy? In those patients who are thought to be good candidates for this treatment, about 70 to 90 percent are found to be free of stones within three months of treatment .
How big does a kidney stone have to be for lithotripsy?
Most kidney stones that develop are small enough to pass without intervention. However, in about 20 percent of cases, the stone is greater than 2 centimeters (about one inch) and may require treatment.
How fast is the speed of dark?
Darkness travels at the speed of light . More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
How long is 1 second in space?
| Light-second | 1 light-second in ... ... is equal to ... | SI units 299792458 m | astronomical units 0.0020040 AU 3.1688×10 − 8 ly 9.7156×10 − 9 pc | imperial/US units 186282 mi |

Can humans survive the speed of light?
Can we travel at the speed of light? No, we cannot travel at the speed of light . You see, if an object travels at the speed of light, its mass will increase exponentially!
How far is lightning per second?
| If thunder is heard The lightning is . . . | 5 seconds after a flash 1 mile away | 10 seconds after a flash 2 miles away | 15 seconds after a flash 3 miles away | 20 seconds after a flash 4 miles away |

What is the fastest thing in the universe?
Light travels about 186,270 miles (more than seven times the circumference of Earth) in one second. In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.
How far does lightning travel per second?
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile , 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
