Objects appear to be different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.
For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt. If only blue light is shone onto a red shirt, the shirt would appear black, because the blue would be absorbed and there would be no red light to be reflected.White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected (Science Learning Hub, 2012).

Use the information in the table above to find out more about the source of the quote that appears at the top of the page.
If you plan to use any part of the quote in your own work then you need to do two things!
One: Once you have pasted all or part of the quote into your work then add the in-line Citation (as shown above) before the full stop.
Two: If you haven’t done so already add an appendix at the end of your work and call it “Reference list” or “Bibliography”. Now add your references (as shown above) in alphabetical order.
