Physics Course/Types of Waves/Light Waves

Light Wave Light wave comes from many sources Fire caused by Flammable and Combustible substance . Luminance Object . Examples Light from Firefly , Light from Luminance Stone Electromagnetic Radiations in the form of Electric Discharge Radiation, Black Body Radiation , Radioactive Decay Radiation , Cosmic Radiation Electromagnetic Radiation as Light Wave Characteristics Electromagnetic radiation as light wave travels at a speed of Light in vaccum C = 3 x 108 and since speed of wave equal product of wavelength and frequency . If one either wavelength or frequency is known then the other quantity can be found by V = λ f = C or . Electromagnetic Light wave has frequency range from few Hz to GHz and divided into the following spectrums Radio Wave Microwave Infrared Visible Light Ultrviolet wave X Ray Gamma Ray Light Wave Phenomenons When Light wave travel through a medium if there is a blocking object that has a height greater than the wavelength of light wave . Light wave will suffer from the following effects Reflection Light wave being reflected back to the medium it comes from and can create interference with other wave in the medium 200px Refraction Only part of the light wave is passing through . Sound does not reach its destination 200px Diffraction Light passing through slits or narrow openings will produce fringes of Light and Dark Pattern 200px Dispersion Light passing through prism will produce Colored Light of the following color Orange , Yellow , Red , Green , Blue , violet 200px Interference When two light waves interfere either Constructively or Destructively to produce Light Interferences like Bright Light , Stream Light , Dim Light , No Light 400px Reference []
