if the time interval between lighting and thunder is 2 seconds.What is the point of lighting if the speed of sound in air is 346m/s?
You can assume for this problem that the speed of light is infinite, about 3*10^8 meters/second which is a lot bigger than 346.
so in the two seconds between the flash and the noise the sound traveled 2*346 meters
To determine the distance to the point of lightning, you can use the speed of sound equation: Distance = Speed × Time.
In this case, we know the speed of sound in air is 346 m/s, and the time interval between the lightning and thunder is 2 seconds.
So, the distance to the point of lightning can be calculated as follows:
Distance = Speed × Time
Distance = 346 m/s × 2 s
Distance = 692 meters
Therefore, the point of lightning is approximately 692 meters away from your location.
