![]() Light waves travel at a faster speed, so we will see the flash before we hear the rumble. The main reason for not hearing thunder at the same time as seeing lightning is that sound waves travel slower than light. Why don’t we hear thunder at the same time as seeing lightning? We hear a more crisp sound when closer because the sound waves of the lighting vibrations have not become distorted by bouncing off surrounding objects. If you are close enough to a lightning strike, you might hear a crack or whip noise. These vibrations travel as sound waves to our ears, and we hear a rumble as a result. Lightning bolts are also very hot, and this immediate heat causes air particles to expand, which creates more force. When the charge happens, it vibrates particles as it moves.īecause lightning is such a large discharge of energy, the vibrations it causes are massive. The rumble that we call thunder is the sound of the vibrations created by the lightning. Thunder is the sound of the lightning bolt. Lightning is the electrical surge created between the cloud and earth, and lightning is the result. This is the same as when you experience a static shock. The charge coming from these ground points will eventually meet the negative particles in the cloud, which causes lightning to strike. The negatively charged particles from the cloud will be attracted to any positively charged particles close by so in things such as mountains, people, or trees. This means that positively charged particles on the ground below will attract the negatively charged particles on the bottom of the cloud. When protons have built up in the cloud, they attract oppositely charged protons around them. Lightning is the bright flash of light or electricity that is caused by a thunderstorm. The buildup becomes positively charged and needs to be released, causing a thunderstorm. Once the electrical charge has built up in the cloud, the positive protons form at the top of the cloud, and the negative protons gather at the bottom. These collisions create an electrical charge. This happens when all the frozen water particles move around the cloud at high speed and bump into each other. The updraft of hot air can be so quick that it forms cumulonimbus clouds.Ĭumulonimbus clouds, more commonly known as thunderstorm clouds, are the only types of clouds that can cause hail, thunder, and lighting.Ī thunderstorm is when a cumulonimbus cloud builds up too much energy. Sometimes these water droplets can freeze while moving around. The hot air rises, and as it reaches the colder air, it forms water droplets. What causes thunderstorms?Ī thunderstorm occurs when there is an unstable atmosphere and where cold air meets hot air. In this article, we will look at what thunder and lighting are and what their causes are. The loud boom of thunder and the striking light produced by lightning can be seen now and again in our skies when we experience a storm. Both thunder and lightning are incredible acts of nature that occur across the globe.
