Tiaexz ends up arriving at Science class in School, they are studying about the heavenly bodies. "So.. why is the sky blue and why does it sometimes even appear red at dusk?", Tiaexz is a little low in mood, he was thoroughly told to "close the zipper" as typical during church, the Science teacher looks towards him and smiles, not the best looking of men, sort of goofy expression and thick rimmed glasses, but always friendly. "Let's take a look and find out how that is then!", the teacher brimmed with a big smile, infront of him were these devices in a box and he begins to bring them out, they look like they have been rescued from the 1970's, but they look function. They basically boiled down to a lampshade with a light bulb within it and a ball within a box. "Whilst we are unable to do this easily with the sun, we should be able to reproduce the effect so you understand", the teacher smiles warmly as he plugs in one of the boxes as the light bulb turns on. "So imagine this is the Sun" the teacher waves it around so you easily get the idea, and he points it towards this ball within the transparent box, "and imagine this is the earth.. as you see, the sun is shining down towards the earth as the sun orbits the sun, rotating like this" the teacher gives a slightly clumsy demonstration, but it is pretty clear what he is trying to do, attempting to make the experience as realistic as possible, "as we learnt, light is made up of different wave lengths, which when they reach the cones within the eye, produce a different colour in our perception, as the light hits upon our earth here, it travels and scatters within the atmosphere, as we see are seeing the blue as per our demonstrationa nd the sky outside, the shorter waves are scattered more when they come in contact with the particles, this scattering fills our senses making us perceive the colour blue, which is a short wave length spectrum. If they are scattered more evenly and more concentrated *light bulb is waved around* it appears 'white' as the scattering is more equal, this is why when you look towards the sun, it appears 'white'", a hand shoots up, "So why does it appear red during dusk or dawn?", the teacher smiles and moves the bulb at an angle towards the ball, from the otherside, the light from the bulb appears reddish. "As you see, when the 'sun' is an angle like this, the shorter wave lengths are scattered away by the particles leaving over the longer wave lengths to penerate".
