Last question has nothing to do with science. One of the better quizzes though.

When did gas pass through a magnifying glass? I always thought it was light.

Marvin Ponton, Frequency determines the pitch of the sound, the higher the frequency, the higher the pitch. The 'loudness' is determined by the amplitude.

10/12, made a couple of foolish mistakes. Better luck next time. Very nice quiz, though--with answers, to boot!

Frequency determines pitch, amplitude or magnitude determines loudness or volume.
Marvin Ponton
I still think that frequency determines the loudness of sound depending on a low or high frequency
