When it thunders, we always see the lightning first and then hear the thunder. What caused this?
1. What caused this? First of all, as long as we have studied junior high school physics, we can know that the speed of light is much faster than the speed of sound. This is a phenomenon that we can always see things and hear the sound first, which is also a normal phenomenon. Many people think that there is something wrong with our health, but this is not the case. This is a normal phenomenon, don't worry too much. You should know that lightning happens at the same time, but because the speed of light is much faster than the speed of sound, we often see lightning first and then hear thunder. Besides, we can often see some other phenomena in our life, which are all seen first and then heard. This is because there are many natural phenomena that cannot be explained by some scientific basis, as long as we know that this is the correct phenomenon. You should know that once it thunders, it will still have a great impact on our health, so try not to go out when it thunders, and it is best to stay at home.
2. The conclusion can be seen that when it rains, besides the occurrence of lightning, it may also lead to lightning. You must know that the direction of lightning is uncontrollable, so you must pay attention to the way to avoid rain in your life. In addition, once lightning occurs, it will represent a rainy season. At this time, we must not be under the tree or near the power line, otherwise it is likely to lead to lightning strike. Give it to us.
