  • 1. Physics for Kids mocomi.com/learn/science/physics/ How Many Colours Does Sunlight Have? Sunlight is made up of a mixture of red, orange, yellow, green, blue, violet and indigo. These colours are the same as that of a rainbow. A prism can be used to see all the colours of the sun. When light passes through a prism, it bends. Each colour can be seen at a different angle. Violet bends the most while red bends the least. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd. All Rights Reserved.
  • 2. How Many Colours Does Sunlight Have? WHY DONT WE USUALLY SEE SUNLIGHT AS SEVEN COLOURS? We assume sunlight to be white it colour. This is because when all the colours are mixed up, it produces white. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd. All Rights Reserved.
  • 3. How Many Colours Does Sunlight Have? ADDITION AL INFOR MATION Light refracts, or bends, when it passes from one medium to another. Every colour of sunlight has a different wavelength. When sunlight passes through a prism, the light separates into its constituent colours with the shorter wavelengths refracting at greater angles than the longer wavelengths. Since violet light has the shortest wavelength, it bends the most; red light has the longest wavelength, so it bends the least. F UN FOR ME!

How Many Colours Does Sunlight Have? ject Pro For more such fun physics articles and videos, visit: http://mocomi.com/learn/science/physics/ Cut out a circle from a piece of card and paint it the colours of the rainbow: red, orange, yellow, green, blue, indigo and violet. Stick a pencil through the middle of the card and spin it. It will look white. Hold a prism up into the sunlight. Direct light through it and see for yourself if you see all the colours of the sun. Watch the experiment "Invisible Glass Trick" on www.mocomi.com to understand 'refraction of light' better. F UN FOR ME! Copyright © 2012 Mocomi & Anibrain Digital Technologies Pvt. Ltd.
