well nothing is faster than the speed of light except possibly neutrinos but that is not yet conclusive, it is about 3.0x108m/s m to give a frame of reference it takes about 8 minutes for the light from the sun to reach the earth, which is not a long time considering how fa that is. the speed of sound is not nearly as fast.

sound travels through our atmosphere at approximately 330 m/s. lightning is just a huge flash of electricity from the cloud to the earth and back. the light we see given off from the strike travels at about 2.99x10^8 m/s. The light is a lot faster than the sound, that's why the thunder (sound) is heard after the flash of lightning is seen.For the actual speed of the lightning strike, it depends on the conditions of the air that it is in but the average is about 4.4x10^5 m/s.

At sea level and through the earth's atmosphere, the speed of light is approx 299,700,000 metres per second. The speed of sound in the same situation is approx 343 metres per second. In vacuum, the speed of light reaches its maximum value, which is 299,792,458 metres per second whereas sound does not travel at all so that its speed is 0.

Light travels at 299,792,458 ms-1 through vacuum.Sound travels at 3243.29 ms-1 through air at sea level. It denser materials it is faster: for example, in iron it travels at 5120 ms-1.
