Answer :

Final answer:

Total internal reflection is crucial in fiber optics for transmitting signals like telephone, internet, and cable TV efficiently.


Explanation:

Total internal reflection is a key principle in fiber optics, where light is transmitted down fibers of glass or plastic. This process allows for the efficient transmission of telephone, internet, and cable TV signals through the fibers by ensuring that light is reflected within the fiber due to specific angle conditions.
