The light travels from the top of the tree (see image), straight through the pinhole, and straight to the bottom of the image.

At the beginning of Debussy's Prélude à "L'Après-midi d'un faune," the flute outlines the interval of a tritone.
<u>Explanation:</u>
Debussy's Prelude starts with the playing of single flute. There are 3 measures. In the piece of measure that is opening the interval of tritone is outlined by the flute. This is done by playing scale in that descends from C-sharp to G and then goes back again to C-sharp.
The fee of an ambiguity is imparted from this interval of tritone. The octave is partitioned into two halves. Here F-sharp, which is a tritone is above one C and a tritone below another C. This similarity in the interval helps the music listeners to identify the pitch that is very important.
WWHWWWH = the Major Scale
That means: two whole steps, a half step, three whole steps, a half step. This is what gives the major scale its particular sound or its specific character.
