Electro magnetic radiation
  1. Light is one form of energy. The light rays consist of tiny particles called photons.
  2. The energy carried by photon is called quantum.
  3. Light is one part of electromagnetic radiation
  4. The other parts of electromagnetic radiation are cosmic rays gama rays, X-rays, ultraviolet radiation, (UR) Infrared radiation (IR) and radio waves.
  5. The visible light is between 400-700nm and lies between UV and IR Radiations 
  6. With increase in the wavelength there is a decrease in energy per quantum.
  7. Visible light has seven different colours (VIBGYOR)
  8. In the visible spectrum, it is near the region of red rays and blue rays, there will be more photosynthesis.
