REFLECTION AND REFRACTION OF LIGHT

  1. 1. Light is the main reason why we can see. Without light, there would be no sight. Itis because our ability to see is due to the interaction between the light, the brain and the eyes.
  2. 2. Reflection is when wave front changes its direction between two differentmedia causing it to return from its point of origin.
  3. 3. incident ray reflected ray According to this law, the angle of incidence is equal to the angle of reflection.
  4. 4. SPECULARREFLECTION DIFFUSE REFLECTION
  5. 5. It is when the direction of the lighttraveling a straight line changes dueto change of medium.
  6. 6.  Refraction occurs when a light ray changes mediums. The speed of light changes when it changes mediums. In almost every case, the direction of the light ray also changes.
  7. 7.  When a light ray enters a new substance perpendicular to the surface of the substance refraction does not occur.
  8. 8.  When a light ray enters a new substance obliquely to the surface of the substance refraction does occur.
  9. 9.  Snell’s law shows the relationship between the angle of incidence and the angle of refraction
