Why do you hear thunder after a bolt of lightning?
Thunder is the sound produced by the rapid expansion and contraction of air surrounding a lightning bolt. When a lightning bolt heats the air to temperatures exceeding 50,000 degrees Fahrenheit, it causes the air to rapidly expand and contract, creating a shockwave that we hear as thunder. The sound travels slower than light, so we often see the lightning before hearing the thunder.
What creates thunder?
thunder is caused when lightning travels over the speed of sound making a sonic boom. also the heat is so enormous it fries the air and ground below it. technically speaking lightning travels from the ground and clouds and meets in the center.
Does thunder travel faster in a storm during winter or summer?
Sound travels faster in higher temperatures because in higher temperatures the molecules collide more often. Thus, as the temperature of the medium decrease, the speed of sound decreases. So in the summer.
With which type of clouds are thunder and lightning often associated?
Thunder and lightning are often associated with cumulonimbus clouds.
When lightning appears in the remote distance and appears to produce no thunder it is called?
When lightning appears in the remote distance and produces little to no thunder, it is often referred to as "heat lightning." This phenomenon occurs when the light from distant lightning strikes travels to the observer without the accompanying thunder, which dissipates over long distances. Heat lightning is typically seen on warm summer nights and is a common misperception that it's a different type of lightning.
Does lightening thunder?
Thunder and lightning occur simultaneously. We often hear the thunder after seeing the lightning due to the distance between us observers and the source of the lightning. Light travels faster than sound, so we see the lightning first and hear the sound later.
What is a small storm accompanied by thunder and lighting and often by precipitation called?
A thunder storm. It has no special name.
How is thunder written in phoneme?
It is often written like Bang! or Crash. These help to describe the sound that is being made by the thunder.
Why is lightning heard before thunder?
Lighting always comes just before thunder because it is the heat of lightning that causes thunder. Lightning is seen when there is a discharge of atmospheric electricity in the clouds or between clouds and the ground. The energy from the lightning heats the air and causes a sudden expansion of the air (followed by a rapid contraction), which results in the sound called thunder. Since the heat of lightning causes the expansion that results in thunder, the lighting must come first. (see related link below) Because light travels faster than sound, an observer will normally perceive a delay between lightning and thunder. This delay increases with farther distance from the actual lightning strike. People will often count the seconds that pass after they see lightning until they hear the thunder. The shorter the time observed between the two, the closer the lightning is to the observer. - In English units, every 5 seconds of delay is about a mile in distance. - In metric units, every 3 seconds of delay is about a kilometer in distance.
Do thunder clouds go flat at the top?
Yes, often they do. This structure is often called an anvil.
Why do you often hear thunder when you see lightning?
You often hear thunder when you see lightning because lightning produces a sudden and rapid heating of the air around it, causing it to expand quickly. This rapid expansion creates a shock wave that we hear as thunder. The farther away you are from the lightning, the longer it takes for the sound to reach you.
What does thunderstorms mean?
A transient, sometimes violent storm of thunder and lightning, often accompanied by rain and sometimes hail.
