At room temperature, sound travels at a speed of about 344 m/s in air. You see a distant flash of lightning and hear the thunder arrive 7.8 seconds later.
How many miles away was the lightning strike? (Assume the light takes essentially no time to reach you.)
Homework Answers
d = vt
= (344 m/s)(7.8 s)
= 2683.2 m
= 1.67 miles

The speed of the sound in air is approximately v=331.4 m/s + (0.6 m/c⋅C)T where T is the temperature in degrees Celsius. The speed of the light is 300000 km/s. The speed of the light is so large that in practical terms, involving distances on Earth, the light travels instantly. On a cool night with air temperature of about 10∘C, you see a lightning flash and then hear the thunder rumble five seconds later. How far is the lightning strike?

Suppose that during a thunder-storm you hear a clap of thunder 6.06 seconds after you see a lightning strike. How far away are you from the lightning strike? Assume room temperature air. Assume light travels so fast that you see the lightning nearly instantaneously.

There is a delay from the time someone sees a flash of lightning to the time that thunder is heard due to the time it takes for sound to travel from where the lightning struck to where you are when you hear the thunder. If you hear thunder 13.6 seconds after seeing the lightning, how far away did the lightning bolt strike? Take the speed of sound in air to be 343 m/s. Answer in metres.

You are watching a lightning storm through your window. You see a big flash of light and you start counting the seconds: one potato, two potatoes, three potatoes... You hear loud thunder when you are at 13 in your counting. If sound travels one kilometer in three seconds, then how far is the storm from you? You can get a pretty good approximation of the distance in miles, if you assume that sound travels one mile in five seconds. What...

It was a dark and stormy night, when suddenly you saw a flash of lightning. Six and a half seconds later you heard the thunder. Given that the speed of sound in air is about 340 m/s, how far away was the lightning bolt? (Ignore the travel time for the flash of light.)

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...

Suppose you hear a clap of thunder 13.4 s after seeing the associated lightning strike. The speed of light in air is 3.00 ✕ 108 m/s. (a) How far are you from the lightning strike? (The speed of sound waves in air is 343 m/s.) km (b) Do you need to know the value of the speed of light to answer? Yes No

Standing on a hill, you see a bolt of lightning hit a building you know is 1900 rods away. How many seconds does it take the sound of thunder to reach you? Use 760 mile per hour for the speed of sound. 16.5 feet = 1 rod and 1 minute = 60 seconds.
