AHA Moments:

We do not see rays of light unless they are reflected from particles of dust or smoke in the air- Sasha and Sharna When something has enough energy it reflects white light - this is because the object has absorbed all the energy it is able to and releases the rest as light - including all colours of the spectrum. - Kate Frosted window glass is translucent but not transparent. -Zac **I found out that light can travel around the world in three times in one second and that when light hits a mirror and reflects off it in water, it makes a rainbow..... LUCY **
 * ﻿I found out that translucent is something light can travel through but the human naked eye can not see through-Kaitlin **

Diffraction occurs when a wave encounters an obstacle. The effects are often seen in everyday life. Examples of diffraction can be displayed involving light. :) Sarah and Lauren. Website: __[|www.launc.tased.edu.au/online/sciences/physics/diffrac.html]__  On this website, there is a diagram on how diffraction occurs. It moves!!! :D

I found out that when you have to mirror next to each other and you place an object in the middle of them the closer you push the mirrors together the object gets more reflections. Megan :P I know why we see colours! We see colours when wave lengths holding white light are reflected,scattered,...by objects on their way to our eyes .- Sasha Laticia and Courtney-A kaleidoscope is one of those toys that you put up to your eye and you can see beads in a triangular pattern,when you spine the little dial at the end they move into a new pattern, kind of like a teloscope.-Sasha. There are special cells in our eyes that help us see colour, if we didnt have these cells we couldnt see colour every thing would be grey- Monique ;p

How do mirrors make patterns??? Megan. :) ﻿How do mirrors make patterns???  Monique :p

The kaleidoscope is a tube of mirrors containing loose coloured beads or pebbles, or other small coloured objects. The viewer looks in one end and light enters the other end, reflecting off the mirrors. Typically there are two rectangular lengthways mirrors. Setting of the mirrors at 45° creates eight duplicate images of the objects, six at 60°, and four at 90°. As the tube is rotated, the tumbling of the coloured objects presents the viewer with varying colours and patterns. Any arbitrary pattern of objects shows up as a beautiful symmetric pattern because of the reflections in the mirrors. A two-mirror model yields a pattern or patterns isolated against a solid black background, while a three-mirror (closed triangle) model yields a pattern that fills the entire field. by kyle
