For a light ray to undergo total internal reflection, light must travel from ( \(i\) = angle of incidence,\(i_C=\) critical angle \()\)
- A rarer to denser medium and \(i < i_c\)
- B denser to rarer medium and \(i < i_c\)
- C denser to rarer medium and \(i>i_c\)
- D rarer to denser medium and \(i > i_c\)
Answer & Solution
Correct Answer
(C) denser to rarer medium and \(i>i_c\)
Step-by-step Solution
Detailed explanation
Condition of total internal reflection: The conditions to be satisfied for total internal reflection are as follows -
1) Light must travel from a denser to a rarer medium.
2) The angle of incidence \(i\) must be greater than the critical angle \(i_C\) the two media.
1) Light must travel from a denser to a rarer medium.
2) The angle of incidence \(i\) must be greater than the critical angle \(i_C\) the two media.
