FAQs on Total Internal Reflection Video Lecture - Physics for JAMB

1. What is total internal reflection?

Ans. Total internal reflection is a phenomenon that occurs when light traveling from a denser medium to a less dense medium is completely reflected back at the boundary, instead of being refracted. This happens when the angle of incidence is greater than the critical angle for the two media.

2. How does total internal reflection occur?

Ans. Total internal reflection occurs when light passes from a medium with a higher refractive index to a medium with a lower refractive index, and the angle of incidence exceeds the critical angle. At this critical angle, the light is no longer refracted but is instead reflected back into the denser medium.

3. What is the critical angle in total internal reflection?

Ans. The critical angle in total internal reflection is the angle of incidence at which the light is refracted at an angle of 90 degrees, parallel to the boundary between the two media. If the angle of incidence exceeds the critical angle, total internal reflection occurs.

4. What are some practical applications of total internal reflection?

Ans. Total internal reflection has various practical applications. It is used in fiber optics for transmitting data over long distances. It is also employed in the design of optical devices like prisms, binoculars, and periscopes. In medicine, total internal reflection is used in endoscopes to enable doctors to visualize internal body parts.

5. How is total internal reflection related to optical fibers?

Ans. Total internal reflection plays a crucial role in the functioning of optical fibers. The fiber core, which has a higher refractive index, is surrounded by a cladding with a lower refractive index. The light signals sent through the fiber undergo total internal reflection at the core-cladding interface, allowing them to travel long distances without significant loss of signal strength. This principle is the basis for high-speed internet and long-distance communication.
