WHAT IS LIGHT 1)The acceleration of electrically charged particles (e.g electrodes, protons or ions). 2)Charging magnetic fields.
 * Light is simply an format of electromagnetic (electric+magnetic)radiation, most familiar to us as visible white light.The light energy is generated by-
 * Like all other waves, it is characterised by wavelengths,frequency, amplitude etc.
 * The velocity of light V=wavelength×frequency.
 * Most important thing is when light passes through one medium to another medium,it's velocity as well as wavelength will change.But it's frequency will remain same.It is also true that frequency is inversely proportional to the wavelength.But during the motion of light,time has a great importance.What is light
