Why does lightning flash before you hear thunder?
If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. We can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder. It takes approximately 5 seconds for the sound to travel 1 mile.
Which color has the lowest amount of energy and why?
Red has the lowest energy and violet the highest. Beyond red and violet are many other kinds of light our human eyes can’t see, much like there are sounds our ears can’t hear. On one end of the electromagnetic spectrum are radio waves, which have wavelengths billions of times longer than those of visible light.
What happens if lightning strikes your car while you’re in it?
Although every lightning strike is different, damage to the antenna, electrical system, rear windshield, and tires is common. The heat from a lightning strike is sufficient to partially melt the antenna of a vehicle and can cause what seems like a small explosion of sparks as tiny fragments of metal melt and burn.
What does it feel like to be struck by lightning?
“It felt like you’d actually been walloped by something, or you were inside a bass speaker.” As the bolt struck, there was a millisecond flash of intense, burning heat, that had already dissipated by the time his brain could even register it.
Is pitch and loudness the same?
Difference between Pitch and Loudness The pitch of a sound is our ear’s response to the frequency of sound. Whereas loudness depends on the energy of the wave. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.
Why do high notes sound louder?
High frequencies are perceived louder than low frequencies by the human ear. So in order to become louder when singing deep notes, more air is required. The deeper you get, the quieter you become, the more air you need.
Why do we see a flash of lightning before we hear the accompanying sound of thunder which characteristic of sound determines how far it can travel before dying out?
Answer: It is because light travels much faster than sound. Hence, flash light of thunder reaches almost instantly, whereas sound of thunder takes time to reach us. Loudness of sound determines the distance it can travel before dying out.
Why is the flash of lightning from clouds seen much before the thunder Although both occur simultaneously?
Thunder and lightning occur at roughly the same time although you see the flash of lightning before you hear the thunder. This is because light travels much faster than sound.
What does sound pitch depend on?
The pitch of a sound depends on its frequency of the vibrating body.
Which characteristics of sound determine how far it can travel before dying out?
Loudness is the characteristic of sound, which determines how far it can travel before dying out.
Why do we hear thunder a few seconds after lightning?
Lightning is a gigantic spark of electricity that connects the thundercloud to the ground. It’s so hot that it causes the air to “explode” — that’s the sound we hear as thunder. However, thunder travels much slower than the light from a lightning bolt, so we usually hear thunder a few seconds after we see lightning.
How many coulombs are in a lightning bolt?
The amount of charge carried by a lightning bolt is estimated at 10 Coulombs.
Why do we hear thunder before we see lightning?
Light travels faster than sound. Light travels at approximately 186,000 miles per second. Sound travels at about 767 miles per hour at sea level. The reason you hear thunder is because when lightning strikes, it is so hot, that the air around the lightning bolt expands faster than the spread of sound, generating a sonic boom.
What does it mean when a flash of lightning is heard?
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!
Which is faster the flash of lightning or the sound of Thunder?
Because light travels much faster than sound. Light travels so fast that you see it practically instantly. However, sound takes about 5 seconds to travel 1 mile (about 3 seconds to travel 1 kilometer). You can use this fact to approximate how far a bolt of lightning was from you using “the flash – bang method”.
What does it mean when thunder sounds like thunder?
Typically, a sharp crack or click will indicate that the lightning channel passed nearby. If the thunder sounds more like a rumble, the lightning was at least several miles away.
