Total internal reflect occurs: A) when moving from a less optically dense (small n) medium to a more optically dense one, for rays near the surface normal
B) when moving from an optically dense (large n) medium to a less optically dense one, for rays near the surface interface
C) when moving from an optically dense (large n) medium to a less optically dense one, for rays near the surface normal
D) when moving from an optically dense (large n) medium to a less optically dense one, for all angles
E) when moving from a less optically dense (small n) medium to a more optically dense one, for all angles
F) when moving from a less optically dense (small n) medium to a more optically dense one, for rays near the surface interface
G) In all situations in which a light ray travels from one medium to another
