and beauty. The flowers rainbow, Sky blue rising and setting sun
impressed man. We see every object with the help of light rays

of light
INTRODUCTION

7. The Phenomenon of splitting of white light in to its components
is known as dispersion
DISPERSION OF LIGHT

8. The whole rang of radiation
from radio waves to gamma rays in the
accenting order of their frequency in
known as electromagnetic spectrum.
When sun light in reelected through
water using an in clined plane mirror
sun light under goes splitting to its
components
ELECTRO
MAGNETIC SPECTRUM

9. When the light from the celestial bodies passes through the atmosphere it
under goes partial and irregular reflection called scattering depends on wave length
shorter the wave length greater the scattering. So the colours like violet indigo blue
scatter. Most thus the stay appear blue
SCATTING TO LIGHT

10. Colour of shorter wave length such as violet indigo and blue
scatter more when compare to other colours of longer wave length
and spread in the sky. The resultant colour of them makes the sky
appear blue.
