Lighting is seen earlier and thunder is heard later because the speed of light is 3×10^8 and the speed of sound is 330 /second. Light travel faster than sound. It's why light is seen earlier than thunder is heard later

Lighting:- during tha rainy season you must have seen sparks in the sky these sparks are tha results of a physical phenomena known as lighting this atmosphere phenomena basically occurred along with a thunderstorm

It is due to high speed of light that we see the flash of lightning first and it is constantly due to low speed of sound that the thunder heard a little later .

Lightning is seen earlier and thunder is heard later because the speed of sound is 330 m/s and the speed of light is 300,000,000 m/s. Light travels faster than a sound. Thus, light from the lightning reaches first to you. The sound from the lightning takes longer to reach and hence heard later That's why see first and then sounds
