Lightning and thunder are generated from a storm cloud at the same time, generating light waves and sound waves. A person a few miles away sees the lightning a few seconds before they hear the thunder. Since the person sees the lightning before hearing the thunder, light waves moved faster from the storm cloud to the person through the air. Why?

light waves move faster through air than sound waves because the air is a vacuum
light waves move faster through air than sound waves because the air is more dense than a vacuum
light waves move between the particles of the air while sound waves move from one particle to the next, since air is a gas the particles are spread out allowing light to move faster than sound
light waves are mechanical waves and require a medium and air is a medium
