Question

To estimate the distance you are from a lightning strike, you can count the number of seconds between seeing the flash and hearing the associated thunderclap. For this purpose, you can consider the speed of light to be infinite (it arrives instantly). Sound travels at about 343 m/s in air at typical surface conditions. How many kilometers away is a lightning strike for every second you count between the flash and the thunder?

Explanation / Answer

Here ,

speed of sound , vs = 343 m/s

for the speed of light very high ,

distance from the lightening for each second

t = 1 s

distance = 343 * 1

distance = 343 m = 0.343 km/s

for the each second , the lightening is 0.343 km away
