while we are headed into the summer, we can start to expect many thunderstorms soon. a thunderstorm is related to physics because of the speed of light and sound. while thunder and lightning occur at the same time, people always hear thunder after they see lightning. the velocity of the speed of sound is 331 m/s, this means that you can measure how far away from a storm you are by counting how many seconds there are from the time you see lightning to the time you hear thunder. for every second in between the thunder and lighting add 331 meters and you will be able to judge how many meters you are from the storm.
