In the Mirror

What I see,

When the mirror faces me,

Is the optical illusion of

diffracted white light,

reflected from the surface of glass:

Its material causes light to enter it under differing wavelengths,

As the inward direction is at an angle,

The consequence is a change in speed,

But because the frequency of visible light

Can never be altered,

light is fractioned,

And a spectrum is formed.

i.e.: A pretty mirror shows me light!

       A rainbow, and it encompasses me!
