How lightnig is formed?

Answer 1

Visible light is simply a small band of the electromagnetic wave emission spectrum, that human eyes respond to, the whole spectrum going from radio (and longer) to gamma (minimum length).

Waves are oscillations which propagate at a constant speed c.

We do not yet understand 'what is waving' and what it propagates through in space, (though many forget that fact and assume we do).

Light is a form of energy that helps us to see objects. it is interesting to note that light is itself not visible. its path is only visible when it is scattered by dust particles present in the atmosphere

Light occurs either when an electron jumps from a higher energy level to a lower one emitting a packet of energy or photon or when matter accelerates to the speed of light as in nuclear reactions. An example of the first would be when electricity excites the atoms of tungsten in a light bulb and the second would be the sun.

Answer 2

When the negative charge in a cloud becomes great enough, it seeks an easy path to the positively charged ground below. The current looks for a good conductor of electricity, or a tall structure anchored to the ground (such as a tree or a tall building). The negative charge sends out a feeler, called a stepped leader, which is a series of invisible steps of negative charges.

As the stepped leader nears the ground, a positive streamer reaches up for it. Only then, once this channel is made, does the visible lightning happen. A return stroke runs from the ground to the clouds in a spectacular flash.

Though the bolt appears continuous, it is actually a series of short bursts. Most lightning strikes occur in less than a half second and the bolt is usually less than 2 inches in diameter.

Answer 3

Ball lightning is thought to be a ball of plasma that is formed when a bolt of lightning hits the ground and creates a molten "hot spot". The ball can typically measure 30 centimeters across and can last for a few seconds.

Answer 4

The particles of cloud which carry a positive charge stay on the top, while those with negative charge become heavy and shift to bottom, afterwards, both cause a spark due to friction and lightning is formed.

Answer 5

Lightning is an atmospheric discharge of electricity accompanied by thunder which typically occurs during thunderstorms. Lightning can also occur within the ash clouds from volcanic eruptions or can be caused by violent forest fires. Ice

Ice inside a cloud is thought to be a key element in lightning development, and may cause a forcible separation of positive and negative charges within the cloud.

The study or science of lightning is called fulminology, and someone who studies lightning is referred to as a fulminologist.

Answer 6

lightening is formed when a positive and a negative cloud collide. The lighting may take place i) between two clouds and ii) between the clouds and the ground. Lighting that hits the ground may kill a person, animal or even start a fire.
