Q: Which of the following is a practical application of total internal reflection?
Solution: Fiber optic communication relies on total internal reflection to transmit light signals over long distances with minimal loss.
Steps: 4
Step 1: Understand what total internal reflection is. It happens when light hits a boundary between two materials at a steep angle and reflects back completely instead of passing through.
Step 2: Learn about fiber optics. Fiber optics are thin strands of glass or plastic that carry light signals.
Step 3: Realize that fiber optic communication uses total internal reflection to keep the light inside the fiber, allowing it to travel long distances.
Step 4: Recognize that this method minimizes loss of light, making it efficient for transmitting data.
