Total internal reflection occurs when light moves from?
A
a dense medium to a less dense medium
B
air to water
C
water to glass
D
a less dense to a dense medium
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Total internal reflection (TIR) is the optical phenomenon in which waves arrive at the interface (boundary) from one medium to another (e.g., from water to air). that is from a more optically denser medium to a less optically denser medium.
