(5). Discarding old and wrong concept of Constructive and destructive interference:– I do herewith introducing a new concept of constructive and transforming (previously termed as destructive)interference, because according to conservation of energy,destruction of energy is quite an absurd proposition. While two crest or two trough of same phase of EMW super imposed on each other it forms bright fringes. Again when crest and trough of opposite phase super imposed on each other form more powerful flat dark energy(so called black fringes) by neutralizing each other. It’s worth while to mention that while electrical and magnetic components proceeded forward perpendicular to the direction of wavefront , there is another component of dark energy(flat dark wave)created and it proceeded along the direction of wave front. The white components EMW is so handicapped that it can not move/run with out riding on dark horse/or dark component of EMW. Hence it is a misstatement/ misconception that velocity of light is three lakh kilometre per second, rather it is more appropriate that it is the running capacity of the dark horse carrying white components on his shoulder. Again this dark component of light is responsible for generating and developing corpuscular nature of light, gravitational lensing, red shift of light,etc. Unique beauty of the presence of dark component( which is introduced by me)of EMW could successfully explain the corpuscular nature of light, gravitational lensing, variable velocity of light and red shift etc. When ever a free flowing light face an white obstruction, the dark component of light could easily penetrate the obstruction leaving behind it’s white components. Then this white components of EMW get puzzled without his carrier(dark component),it is then rolled in like a ball(just like thread in a bobbin). Which is then reflected /deflected as photon ball, indicating dual corpuscular nature of light, which indicates that EMW have dual character,i.e, wave character and particle character. When light passes near the larger remnants, it got attracted towards large remnants due to the presence of dark gravitational component of EMW and producing multiple images of the same object(as shown in picture) which is known as gravitational lensing. When EMW approaches to ward event horizon of the black hole, the velocity of light got slower and slower and ultimately stopped because the dark part of the EMW readily enter in to the black hole (while approaching near the Singularity/dark dump) leaving behind its white components of EMW outside the black hole due to strong attractive force of the central Dattom dump or so called singularity present in the black hole. As a result of which velocity of light slowed down and light become dimmer and dimmer which is known as Red shift of light with lesser energy and ultimately stopped, until white EMW completely transformed into dark energy.As a matter of fact energy of EMW rapidly loses it’s energy producing Red shift of light. Bright and black fringes is observed during diffraction of light occurred while strong light is passes through pin hole of a close black box as shown in picture. It was previously presumed that black fringes are formed due to destructive interference indicating absence of energy. But actually it’s nothing but the dark energy fringes formed by transforming interference.
