  Ultraviolet (UV) :<\/h2>\r\n\r\n\r\n\r\n

  \r\n
  • Electromagnetic radiation with a wavelength from 10 nm to 400 nm, shorter than that of visible light but longer than X-rays.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n\r\n\r\n

    Refractive index :<\/h2>\r\n\r\n\r\n\r\n

    \r\n
    • The refractive index, also known as the index of refraction, is defined as the ratio of the velocity of light in vacuum (or air) to its velocity in a transparent medium.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n

      PDA – Photo Diode :<\/h2>\r\n\r\n\r\n\r\n

      \r\n
      • A photodiode is a semiconductor device that converts light into an electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
