Sabrina was struck by lightning and was lucky not to get badly hurt.

Every 5 seconds between when you see lightning and when you hear the thunder is one mile. You can practice this with a clock to get the timing right if you want. If you say "one thousand one, one thousand two, one thousand three", you have counted about 3 seconds. Use a watch or clock with a second hand or count the seconds. So, if you time how long it takes to hear thunder after you see lightning, you can find out how far away the lightning struck. This is caused by the slower speed of sound. You hear where it was a little while ago. You can see where the plane is right now. Where do you see the plane? Where do you hear the plane? If the jet is flying high, there will be a distance between where the plane can be seen and where it can be heard. Go outside and watch as a jet flies overhead. It takes sound about 5 seconds to travel one mile. Thunder travels much slower, at the speed of sound, about 1088 feet per second. When lightning strikes, a noise is made which we call thunder. This means that you see lightning pretty much when it happens. Lightning travels at the speed of light, about 186,000 miles per second. It is possible to use thunder and lightning to measure how far away a storm is. What day do you first hear thunder? What was the weather like the day before, warmer or colder? What is the weather like after the thunderstorm, warmer or colder? It might be fun to keep track of the first thunder and lightning of the year. According to Wikipedia.With the start of spring typically comes thunderstorms. But now we know that the speed of sound depends on the temperature and the medium through which a sound wave is propagating.Īt 20 ☌ (68 ☏), the speed of sound in air is about 343 metres per second (1,125 ft/s 1,235 km/h 767 mph 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s. The advanced F-22 Raptor can achieve and sustain supersonic speeds without having to ignite its afterburners. In altitudes above sea level the speed of sound is again different and will vary depending on prevailing factors. He assumed that the speed of sound is 478.4 metres per second (1,569.6 feet per second). At a temperature of 32-degrees Fahrenheit (0 Celsius) the speed of sound drops to 742 mph (1,194 km/p/h). He started experimenting with the sound of the gunshot and measured the sound of the shot at a distance. In the early 1700s, a French scientist by the name of Pierre Gassendi made one of the earliest attempts to measure the speed of sound. If the sound is a wave, then what is the real speed of the sound? When Galileo Galilei recorded the relationship between the frequency of the wave to the pitch it produces, people started questioning the speed of sound. Measuring Speed of Sound: What is the exact speed of sound in real life? Answering this question isn’t that complicated, but at the same time, it isn’t too easy.
