How can I rename a lot of files with a single command?

I have a lot *.WAV files, I want all them to be *.wav (lowercase)... I have foo.WAV I would doo mv foo.WAV foo.wav and that's it, but what if I have more than one (with a single command) ?

Uhm... it says that 'misses a file as an argument'. By the way, how that stuff about advanced commands like sed and so (perl regular expressions?) are called so I can learn more about them?
