An oscilloscope is a machine that gives a picture of a sound wave. Low-pitched sounds have wide waves, and high-pitched sounds have thin waves. Which sound below has the highest pitch? F G H J
Probably J because it's higher in the lettering so it's also probably higher in high note ness, because I play the piano, I know this, the more frequency the more the pitch and the higher the pitch which is higher in the keyboard is higher in pitch.
