Sound produced by a thunderstrom is heard 10 s after the lighting is s? ›

Lightning reaches the observer with a very large speed, i.e., with the speed of light (3×108m/s). Thus the entire time of 10s between the seeing of lightning and hearing of thunderstorm is taken by the sound to travel to the observer. Hence, distance of the thunder cloud i.e., s=vt=(340m/s)(10s)=3400m=3.4m.

Sound produced by a thunderstorm is heard 10 s after the lightning is seen. The approximate distance of the thunder cloud : (Given speed of sound =340ms1) 3.4 Km.

Thunder is the sound caused by a nearby flash of lightning and can be heard for a distance of only about 10 miles from the lightning strike. The sound of thunder should serve as a warning to anyone outside that they are within striking distance of the storm and need to get to a safe place immediately!

At large distances from the center, the shock wave (thunder) is greatly elongated and can be many miles across. The combination of millions of shock waves gives thunder the continuous booming/rumbling sound we hear.

The most noticeable aspect of lightning and thunder is that the lightning is seen before the thunder is heard. This is a consequence of the speed of light being much greater than the speed of sound. The speed of sound in dry air is approximately 343 m/s (1,130 ft/s) or 1,236 km/h (768 mph) at 20 °C (68 °F; 293 K).

If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.

In nature, a lightning flash and the associated thunder occur at almost the same time in a thunderstorm. A person on the ground sees the lightning flash before hearing the thunder because light at a speed of around 300,000,000 meters per second travels much faster than sound which moves at 340 meters per second.

The velocity of light which is equal to 3 × 108 m/s is much greater than the velocity of sound which is equal to 344 m/s. Hence, we see the flash of lightning much before the sound of thunder reaches us.

Since, the speed of light is much greater than the speed of sound, so during lightning, the flash is observed way before the thunder is heard.

Sounds of thunder

A “crack” is typically indicative of a nearby or relatively close thunderstorm and/or with a strike perpendicular to a person (ex. lightning bolt stretching from the cloud to the ground). A “rumble” is typically associated with storms further away and/or with a strike parallel to a person (ex.

What are the two sounds of thunder in A Sound of Thunder? ›

e.g. "A sound of thunder" first means the sound of the dinosaur's step; then it means the firing of the rifle that kills Eckels.

In 'A Sound of Thunder,' the title symbolizes the approach of danger. Within the story, Bradbury uses the phrase found in the title twice, once when the Tyrannosaurus is approaching the hunters and once when Travis raises his rifle to shoot Eckels at the end.

Cloud to Cloud: Lightning that occurs between two or more separate clouds. Cloud to Ground: Lightning that occurs between the cloud and the ground. Cloud to Air: Lightning that occurs when the air around a positively charged cloud top reaches out to the negatively charged air around it.

If lightning occurs a kilometer away, the light arrives almost immediately (1/300,000 of a second) but it takes sound nearly 3 seconds to arrive. If you prefer to think in terms of miles, it takes sound nearly 5 seconds to travel 1 mile.

All gases expand when the temperature increases, so when lightning superheats the air at just a fraction of a second, the air expands so rapidly that it compresses the air in front of it. Thunder is the acoustic soundwave generated by this quick expansion and contraction of air.

Amplified thunder

In a typical ground-based storm, thunder dissipates in all directions, a quick loud boom or rumble. However, in a temperature inversion, the sound becomes trapped and refracts back to the ground. This trapping and refracting can cause the thunder to be amplified, making it sound louder than normal.

With nearby lightning strikes the thunder will sound like a loud bang, crack or snap and its duration will be very short. As the shock wave propagates away from the strike center, it stretches, diminishes, and becomes elongated. Then other shock waves from more distance locations arrive at the listener.

If you can't hear thunder, that usually means you're more than 6 to 10 miles from a thunderstorm; and that's the typical maximum distance lightning can strike to the side. For more information on thunderstorm safety, check out my book "Lightning Strikes", by Mountaineers Books.

That's because light travels faster than sound. To be exact, it travels 882,353 times faster! So even though lightning and thunder happen at roughly the same time, you don't hear thunder until much later than you've seen the lightning.

“Crack” is the real sound of lightning as it tears through the air; it's actually an explosion occurring along a very long path (up to about a few km). It is usually heard when close enough to the source.
