JOURNEY OF LIGHT Light is the most important phenomena around us .It makes us see things of this world. ... What is the nature of light? ... The phenomena of reflection and refraction was explained on the basis of elastic collision and attraction of light by dense medium particles respectively. ... The nature of light seemed to be established . ... He came up with the theory of dual nature of light. ...
These telescopes captured light that was emitted from these stars in space. ... Galileo was the first astronomer to use a refracting telescope. ... They both captured the incoming light and bent it into a bright point where the viewer may see the desired object. ... Generally, solids, liquids, or dense gases emit light at all wavelengths when heated. An absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives ...
Our eyes are detectors, which detect visible light waves. ... There are other forms of light, which we cannot see. ... All forms of radiation travel at the speed of light. ... Hershel performed other experiments called "calourific rays" that existed beyond the red part of the spectrum and found that they were reflected, refracted, absorbed and transmitted just like normal light. Sir William has discovered a form of light beyond red light. ...
