Photonics Is the Science and Technology of Generating,Controlling, and Detecting Photons, Which Are Particles of Light – By Emission,Transmission, Amplification, Detection, and Modulation of Light. the 21Stcentury Will Be As Dependent on Photonics As the 20Th Centurydepended on the Electronics. Photonics Explores a Wider Variety of Wavelengthsthan the Electromagnetic Spectrum, from Gamma Rays to Radio, Including X-Rays,Uv and Infrared Light. the Characteristics of the Waves and Photons Can Helpexplore the Universe, Cure Diseases, and Might Even Solve Crimes.
