LIGHT

LIGHT  IS  A   FORM  OF  ENERGY.It   is  a  type of  electromagnetic   radiation , like-X-rays or  radio  ways.All  electromagnetic radiation  is  produced  by  electric  charges,it  is  caused  by  the  effects    of     oscillating   electric  and  magnetic  fields   as they  travel through   space.Electromagnetic   radiation  is  considered    to  have   both wave  and particle   properties.It  can  be  thought  of  as  a wave  electricity  and  magnetism .In  that  case ,  the  difference   between   the  various  forms   of  radiation is  their  wavelength.Radiation  can  also  be   said  to  consist of  particles packets of  energy called   photons.The  difference  between  light  and   X-rays  instance is the  , amount   of  energy  that   each photon  carries.The   complete   range  of  radiation  is referred     to as  the   electromagnetic    spectrum, extending   from  low  energy,long  wavelength  radio waves to  high  energy  ,short wavelength    gamma  rays.
    
    
Light  is  the  only  part of    the  electromagnetic    spectrum  that is visible.White   light  from  the  Sun   is  made  up  of all  the  visible  wavelength  s  of  radiation,which   can  be  seen  when  it  is  separated   by  using  a  prism.Light  ,like  all form  of  electromagnetic  radiation,  can  be  reflected(bounced back)  and   refracted(bent)different  parts   of   the  electromagnetic   spectrum  are  produced in   different  ways.Some  time  visible  light- and  infra-red radiation-  is  generated  by vibrating  particles of  warm  and   hot  objects.
The  emission   of  light   in  this  way   is  called incandescence,  a  phenomenon  in    which   electrons  gain  and  lose   energy   within  atoms.
