3 Total Internal Reflection

  1. 1. TOTAL INTERNAL REFLECTION OF LIGHT
  2. 2. TOTAL INTERNAL REFLECTION OF LIGHT N INCIDENT RAY REFRACTED RAY
  3. 3. CONDITION <ul><li>The two conditions for total internal reflection to occur are: </li></ul><ul><li>Light enters from a denser medium towards a less dense medium </li></ul><ul><li>The angle of incidence in the denser medium is greater than the ciritical angle of the medium </li></ul>
  4. 4. Critical Angle (c) <ul><li>The angle of incidence in the denser medium when the angle of refraction in the less dense medium is 90 o . </li></ul>
