Which of the following phenomena is NOT a result of total internal reflection?

Which of the following phenomena is NOT a result of total internal reflection?

Correct Answer: Prism dispersion

Step 1: Understand what total internal reflection is. It occurs when light hits a boundary at a steep angle and reflects completely back into the medium.
Step 2: Identify the phenomena that result from total internal reflection. Examples include fiber optics and the sparkle of diamonds.
Step 3: Look at the options given in the question. One of them is prism dispersion.
Step 4: Know that prism dispersion happens when light passes through a prism and bends (refracts) at different angles, separating colors.
Step 5: Conclude that prism dispersion does not involve total internal reflection, while the other options do.
