Q. The lightning is seen before we hear thunder because
Solution:
- Lightning is an electrical discharge that occurs in the atmosphere, and it travels at the speed of light, which is approximately 299,792,458 meters per second.
- Thunder, on the other hand, is the sound produced by the rapid expansion of air that occurs as a result of the lightning discharge.
- It travels at a much slower speed than light, which is approximately 343 meters per second.
- The reason why we see lightning before we hear thunder is that light travels much faster than sound, and therefore it reaches our eyes before the sound reaches our ears.
- The time interval between seeing the lightning and hearing the thunder can be used to estimate the distance of the lightning strike, as sound travels at a constant speed and the distance can be calculated using the formula distance = speed x time.
