Sunlight - white or coloured
- The sun is the biggest source of light on the earth.
- The sunlight is white in colour however this white light often disperses into several colours which results in different colours of the sky at different times of the day.
- The white light consists of seven colours namely VIBGYOR (violet, indigo, blue, green, yellow, orange and red).
- This arrangement of seven colours of white light is called Spectrum.
- All these colours mixed together and form the white light. However, due to the reflection of light, the seven colours can split and be seen as separate colours rather than a single white light.
- This phenomenon of the splitting of light into its constituents is called Dispersion of light.
Examples of Dispersion of Light:
- Formation of the rainbow due to the dispersion of white light through the water droplets.
- Passing of Sunlight through a prism
- Dispersion of light through the soap Bubbles
- Dispersion of light on the CDs
