In summary, the speed of sound is approximately 346 meters per second and it is related to the distance of lightning. The distance of lightning can be calculated by dividing the time between seeing the flash and hearing the thunder by 3.4. If the thunder is heard 10 seconds after seeing the flash, then the distance of lightning is approximately 3,460 meters. The speed of sound is not constant and can vary depending on factors such as temperature, humidity, and altitude. The distance of lightning can help determine the intensity of a storm by providing information about the distance of lightning strikes. The sound of thunder can vary due to the distance of the lightning strike and the terrain it travels through.

The sound of a thunder is heard 3 seconds after the lightning. If the speed of sound is 346 m/s find the distance from where the lightning occured?

the speed of light is 3 x 10^8 m/s

let the distance be x m, and then come out with a simultaneous equation.

Related to Distance of Lightning from Sound:346m/s

1. What is the speed of sound and how is it related to the distance of lightning?

The speed of sound is approximately 346 meters per second at sea level and room temperature. It is the rate at which sound waves travel through a medium, such as air. The distance of lightning can be calculated by dividing the time (in seconds) between seeing the flash and hearing the thunder by 3.4 (since sound travels at 346 m/s).

2. How far away is lightning if we hear thunder 10 seconds after seeing the flash?

If we hear thunder 10 seconds after seeing the flash, then the distance of lightning is approximately 3,460 meters (10 seconds divided by 3.4).

3. Is the speed of sound constant or does it change?

The speed of sound is not constant and can vary depending on factors such as temperature, humidity, and altitude. It generally increases with increasing temperature and humidity, and decreases with increasing altitude.

4. How does the distance of lightning help us determine the intensity of a storm?

The distance of lightning can help us determine the intensity of a storm by providing information about how far away the lightning strikes are occurring. The closer the lightning is, the more intense the storm is likely to be. This can help us make decisions about seeking shelter and staying safe during a storm.

5. Why does thunder sometimes sound like a rumble or a crack?

The sound of thunder can vary depending on the distance of the lightning strike and the terrain it travels through. A low rumble can be heard when the lightning is far away and the sound waves have to travel through a lot of air. A sharp crack can be heard when the lightning is closer and the sound waves have less distance to travel. The terrain can also affect the sound, with mountains and buildings causing echoes and changes in the sound's intensity.
