W: Did you hear the thunder last night
M: Did I It was really loud.
W: I didn’ t see any lightning, though. I thought that thunder and lightning always occur at the same time.
M: They do. It’ s no possible to have one without the other since thunder is a direct result of lightning.
W: Really
M: Yes. Thunder is caused by the rapid expansion and contraction of highly heated air along the path of an electrical discharge.

W: I wonder if it’ s possible to see the lightning and not to hear the thunder.
M: Yes. It’ s possible if the lightning flashes far enough away. Sound doesn’ t travel as far as light.
