Description: How do we see colour? What are colours? In this educational cartoon we briefly explain how we see objects and why we see different colours – without showing wavelengths/frequencies (to keep it simple, at elementary school level). We help children understand such terms as spectrum and dispersion. Rays of light coming from the Sun or a lamp hit the object and are reflected from it, like from a mirror. Reflected rays fall into our eyes, and we see an image of the object. Because of light, we can not only see objects, but also distinguish their colour. Sunlight is white. But white colour is actually a complex colour, it is made up of all the other colours. The great physicist Isaac Newton proved it. He took a transparent prism and sent a beam of sunlight through it. White light actually includes rays of different colours. When they mix, we see white light. The prism separates the rays and we saw different colours individually. The light, decomposed into separate colours, is called SPECTRUM. The splitting of light into a spectrum is called DISPERSION. We observe this phenomenon in nature when we see a rainbow. Water droplets, like small prisms, also spread sunlight into a spectrum. we see an object due to the fact that it reflects the light falling on it. However sunlight is made up of rays of different colours. Objects of different colours reflect rays of their own colour. For example, red objects absorb all rays except red rays which are reflected back into our eyes.
