Sound waves can also bounce off molecules in the air causing it to travel in different directions.
Since lightning is also very hot up to 6 times hotter than the surface of the sun it makes the air around it expand very quickly which creates more vibrations as the particles get pushed.

The speed of light depends on what it is moving through being slow in gases fast in liquids and even quicker in solids.
