Light Reflection


Published on

Published in: Technology, Business
  • Light and its nature have caused a lot of ink to flow during these last decades. Its dual behavior is partly explained by (1)Double-slit experiment of Thomas Young - who represents the photon’s motion as a wave - and also by (2)the Photoelectric effect in which the photon is considered as a particle. A Revolution: SALEH THEORY solves this ambiguity and this difficulty presenting a three-dimensional trajectory for the photon's motion and a new formula to calculate its energy.

Light Reflection

  1. 1. Light<br />Reflection of Light<br />
  2. 2. Reflection<br />When a light ray hits a non-luminous object, it is either reflected or absorbed.<br />The light ray which hits the object is called the incident ray.<br />The light ray whichbounces off is called the reflected ray.<br />The normal to a surface is a line that runs the perpendicular to the surface.<br /><ul><li>Normal
  3. 3. Incident Ray
  4. 4. Reflected Ray</li></li></ul><li>Laws of Reflection<br />First Law of Reflection states that the incident ray, reflected ray and the normal all lie in the same plane.<br />Second Law of Reflection states that the angle of incidence, i ,is equal to the angle of reflection, r.<br />r<br />i<br />
  5. 5. Regular & Irregular reflection<br />The two kinds of reflection is dependent on the surface of the object where the light hits.<br />The laws of reflection is true in both regular and irregular reflections.<br />
  6. 6. Mirrors<br />Surface is smooth.<br />Light is reflected completely.<br />=<br />=<br />Image is…<br /><ul><li>Upright
  7. 7. Virtual
  8. 8. Same size as object.
  9. 9. Same distance from the mirror as the object.</li>
