Question

Which of the lightning and thunder come first during rainy day?and give reason

Answer 1

Thunder and lightning happen at approximately the same time, but as you have heard, lightning travels faster than thunder (even though it is moving a supersonic speeds) and thus we see the flash before we hear the thunder.

The speed of sound through air is about 340 meters per second. The speed of light in air is about 300 million meters per second.

So due to this we see the lightening first and then hear the thunder
