Light
There are many theories about how light travels through space, in particularly and most commonly highlighted in research is particle theory of light and wave theory of light. The particle theory of light suggests that light acts like particles, (little bullets of light) that stream from the source. This theory explains how shadows work. Whereas the wave theory suggests that light also acts in a wave like motion, similar to ripples in space. The farther you are away from the
Isaac Newton was a very famous English scientist who made a break through discovery in relation to light. He realised that white light is not just white light, it is also made up of all colours at once, as well as discovering that a piece of glass, when used correctly, has the ability to separate the colours from one another.
Spectral lines demonstrate that every element has a particle theory related to it. When a photon comes into contact with an element's atom, the light is absorbed. A photon is a light particle. When this occurs it creates dark bands in the spectrum at particular frequencies. Due to its colour you are able to identify the chemical compositions of a star/s. Colours in a spectrum consist of: No colour, Red, Orange, Yellow, Green, Blue, Indigo and Violet. A way to remember all these colours in order is to create your own rhyme. For example: Richard Of York Gave Battle In Vain.
The only electromagnetic wave visible to the human eye is visible light. Visible light produces different types of colours depending on their wave frequency. For example, when a light wave is really short it will appear violet, and when they appear all together, the light is white. Below are the frequencies of wave lengths, determining their colour.
Red: 625-740 Orange: 590-626 Yellow: 565- 590
Green: 520-565 Blue: 435-500 Violet: 380-435
