Some call that heat lightning, but it is really lightning that is over 15 miles away and too far away for you to hear the thunder! LOOK OUT if you see the lightning and hear the thunder at the same time!
Best Answer: Thunder is the sound of rapidly heated air expanding and vibrating, and shock waves. Light travels faster than sound, so we see the lightning before we hear the resulting thunder. Using the speeds of light and sound as well as the atmospheric conditions, you could calculate exactly how far away the storm is. Chances are you're not going to have a calculator handy during a storm.
