Presentation transcript:

How far away is the storm? Light travels much faster than sound. If you are near a thunderstorm you can determine approximately how far away the storm is by counting the seconds between when you see the flash and when you hear the thunder.

The Math Take the number of seconds between flash and sound. Multiply this number by 1,200 (approx speed of sound ft/sec) then divide by 5280 Check your math with a storm distance calculator. http://www.csgnetwork.com/lightningdistcalc.html
