Why do we see lightning before we hear thunder?

• The lightning forms before the thunder does.

• Sound travels faster than light.

• Light travels faster than sound.

• The ears transmit information more slowly than the eyes.

How do sound waves move in air?

• The wave particles diffract around a barrier.

• The wave particles displace one another, with particles replacing each other.

• The wave particles move via acceleration; that is, they increase speed.

• The wave particles move in a curvilinear motion.
