What is thunder and how thunder caused sound ?
Thunder is the sound that lightning makes. Sounds simple but why does lightning make a sound. Any sound you hear is made up of vibrations, the vibrations travel through the air as waves until they reach your ear. This means lightning must cause some vibrations. Lightning is a huge discharge of electricity. When lightning strikes huge amounts of electricity shoots through the air, this causes two things to happen. 1. The electricity hits the air and starts it vibrating, anything vibrating causes a sound. 2.The lightning is also very hot and heats up the air around it. Hot air gets bigger: it expands. As lightning is very hot the air gets bigger very quickly and pushes against the air particles starting another vibration. These vibrations are what you are hearing when you hear thunder, the rumbling of thunder is caused by the vibration or sound bouncing of the ground and the clouds. Sources: http://www.sciencemadesi
Thunder is the sound made by lightning. Depending on the nature of the lightning and distance of the listener, it can range from a sharp, loud crack to a long, low rumble (brontide). The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave which produces the sound of thunder. [edit] Cause The cause of thunder has been the subject of centuries of speculation and scientific inquiry. The first recorded theory is attributed to the Greek philosopher Aristotle in the third century BC, and an early speculation was that it was caused by the collision of clouds. Subsequently, numerous other theories have been proposed. By the mid-19th century, the accepted theory was that lightning produced a vacuum. In the 20th century a consensus evolved that thunder must begin with a shock wave in the air due to the sudden thermal expansion of the plasma in the light
