Hello and welcome to our Blog!

We are a group of Year 1 and 2 students that are hoping to create a table-top, virtual rainbow. We are Yepyep.

Yepyep consists of Azzam, Kelvin, Javier and Gerald.

You might be thinking: “Making rainbows? How hard could that be?” and  “All you need is a prism/CD.”

Well, the definition of the word “Rainbow” is: “An arch of colours visible in the sky, caused by the refraction and dispersion of the sun’s light by rain or other water droplets in the atmosphere. The colours of the rainbow are generally said to be red, orange, yellow, green, blue, indigo, and violet.”

The prism/CD method does not actually create an arch of colours, so technically isn’t a rainbow, and the “rainbows” from the prism/CD method creates a real image of the spectrum of colours; i.e. the image has to be projected on a screen to be visible. We are trying to replicate the rainbows that you are most familiar of, the ones formed after a rainy day. These rainbows are actually virtual images, much like the images you see in your mirror everyday. That’s because the rainbows you see in nature are indeed reflections.

Rainbows are a meteorological events, and we hope to be able to recreate this phenomena on a table-top setup. This blog will be used to document our journey of creating table-top rainbows.
