A modern wireless electrical device should be perfectly safe, all it is is putting a metal piece near your ear, basically giving you the same chance of being hit by lightning as any other time. Older (Or more accurately, larger) technologies with larger antennas might work as a lightning rod, and thus give you a somewhat higher chance of being hit.

Aug 25, 2018 · You are confused about units. Watt is a unit of power (energy/time), Watt-hour is a unit of energy. 16TW is an estimate of the continuous average power usage of the world - which is about 140,000 TWh each year. If the lightning has a peak power of 1TW for 30 microseconds, this corresponds to an energy content of about 8000 Watt-hours.

Jan 27, 2022 · The sound barrier theory is complete nuts. However, lightning does not travel at the speed of light. In fact, when the voltage between the cloud and the Earth reaches a critical level, many small low-intensity lightning bolts propagate more or less randomly downwards, ionizing the air along the way, forming a channel of conductive ionized air.

Mar 21, 2014 · More boom, less rumble - closer. More rumble, less boom - farther away. My rough estimation is that if the lightning is more than two or three miles away (10 - 15 second gap between lightning and thunder) you won't hear it much, although farm animals and pets may get nervous. $\endgroup$ –

Jul 18, 2013 · There seems, however, no doubt that lightning gives two different spectra, one of bright lines, and the other continuous;] unless indeed the latter be identical with the former, but with the lines much expanded. this paper. and a bunch of others. So, in conclusion, why lightning emits light is because:

Dec 28, 2022 · However a very close strike was perceived with the eye - and the power of the house tripped at the same time as the lightning strike was seen (exactly 20m). However the "crack" sound of the initial thunder (not the echo) was delayed - …

Thus, the processes involved in generating lightning directly and indirectly result in the generation of electromagnetic (i.e., UV to gamma rays) and particle (i.e., the free electrons responsible for the kiloamp currents) ionizing radiation. In summary, lightning is a very different beast than fire, which is just a chemical reaction.

Lightning strike locations are psuedo-randomly dispersed. If a thunder storm develops over, say, a 100 square kilometer PERFECTLY FLAT area, and throws out 100 strikes, then the expected strike coverage is 1 strike per sq. kilometer.

Apr 11, 2021 · When a lightning is produced, the air is heated up to a very high temperature, creating a shock wave like. The sound heard depends on the position of the observer, far way or near the thunder origin, and the shape and direction of the thunderbolt. Lightning can be cloud to cloud or ground to cloud and they can have vertical or horizontal direction.

Jul 24, 2017 · The current in a bolt of lightning varies with time, but is not periodic, so it can be represented as either a DC or an AC current. This is because any time-varying DC current can be represented as a superposition* of AC currents (here meaning sine or cosine functions), the amplitudes of which are constant in time.
