Comparison of thunder and lightning

Thunder and lightning are formed simultaneously.

We know that the speed of light in air is

3×108 m/s .

The speed of sound in air is

330 m/s .

Since, the speed of light is much greater than the speed of sound, so during lightning, the flash is observed way before the thunder is heard.
