Question:

The essential condition for total internal reflection to occur is:

Options:

angle of incidence $i$ > critical angle $i_c$

angle of incidence $i$ < critical angle $i_c$

angle of incidence $i$ = critical angle $i_c$

angle of incidence $i=90°$

Correct Answer:

angle of incidence $i$ > critical angle $i_c$

Explanation:

The correct answer is Option (1) → angle of incidence $i$ > critical angle $i_c$
