Total internal reflection occurs when light travels from a:
A
Denser medium to a rarer medium at any angle
B
Rarer medium to a denser medium
C
Denser medium to a rarer medium at an angle greater than the critical angle
D
Vacuum to a medium
Correct Answer: Option C — Denser medium to a rarer medium at an angle greater than the critical angle
Explanation:
Total internal reflection occurs when light traveling from a denser to a rarer medium strikes the boundary at an angle greater than the crit...
Total internal reflection occurs when light traveling from a denser to a rarer medium strikes the boundary at an angle greater than the critical angle, causing it to be completely reflected internally.
