If you’re outside and you see lightening, you should always take cover. Then, it is interesting to figure out how far away the lightning really is. You can do this using the properties of sound waves. Assume the velocity of sound is 350 m/s as it travels through the air and you hear the thunder after you’ve seen the bolt of lightning in 2 seconds. How far away is the lightning in km?

Select one:

a. 17 km

b. 1.2 km
