Answer:
Fiber optic cables
Step-by-step explanation:
Total internal reflection is the reflection of light when
• it travels from a more dense medium to a less dense medium
,
• the angle of incidence exceeds the critical angle
The technological application of total internal reflection is seen in fiber optics cables in which there is a transmission of light down fibers of plastic or glass.
The cladding of the fiber optics prevent light from being transmitted in a bundle.
