What is the Difference Between Lightning and Thunder?

🆚 Go to Comparative Table 🆚

Lightning and thunder are two separate phenomena that occur during storms and are related to each other. The main differences between them are:

  1. Nature of the phenomenon: Lightning is a discharge of electrical energy, while thunder is a sound caused by the lightning's rapid heating and cooling of the surrounding air.
  2. Speed: The light from lightning travels at a speed of 670 million mph, while the sound of thunder travels at 768 mph.
  3. Temperature: Lightning can heat the air to as high as 50,000 degrees Fahrenheit.
  4. Distance: Thunder can be heard up to 10 miles away from the lightning source.
  5. Causality: Lightning causes thunder, but thunder does not cause lightning.

In summary, lightning is an electrical discharge that occurs during storms, while thunder is the sound created by the rapid heating and cooling of the air surrounding the lightning. Both phenomena are dependent on each other but are separate events.

Comparative Table: Lightning vs Thunder

Here is a table summarizing the differences between lightning and thunder:

Feature Lightning Thunder
Definition Electrical discharge produced by charged clouds Sound caused by the rapid heating/cooling of air due to lightning
Speed Travels at 670 million mph Travels at 768 mph
Temperature Can heat the air to as high as 50,000°F Causes rapid air expansion and contraction
Distance Can be seen up to 25 miles away Can be heard up to 10 miles away
Source Caused by electrically charged clouds Lightning is the source of thunder
Potential Can cause damage, including fatalities Scary, but has little potential to cause damage

Lightning is an electrical discharge produced by charged clouds, while thunder is the sound caused by the rapid heating and cooling of air due to lightning. Lightning travels at a faster speed than thunder, and it can be seen from a greater distance. Thunder serves as a warning sign that a lightning strike has occurred nearby, but it generally has little potential to cause damage.
