Correct Answer:C
An upper endoscopy is a procedure used to visually examine your upper digestive system with a tiny camera on the end of a long, flexible tube.
Basically, a typical endoscope uses fiber optics, which allow for effective transmitting of light. The optical fiber allows for light to travel through curved paths, which makes one of the best systems to view spaces that would normally be difficult to reach. Here, total internal reflection makes it possible for light to travel along the fibers with the light rays hitting the fiber walls at an angle (minimum angle of 82 degree).

Understanding Endoscopic Processes
Endoscopy is a medical procedure that allows doctors to view the inside of a patient's body using a flexible tube with a camera and light source. The principle that enables this visualization is based on total internal reflection of light.
What is Total Internal Reflection?
- Total internal reflection occurs when light travels from a denser medium to a less dense medium at an angle greater than the critical angle.
- In endoscopes, this principle is utilized to transmit light and images through optical fibers.
How It Works in Endoscopy
- Light Transmission: The endoscope contains numerous optical fibers that guide light. When light is sent through these fibers, it reflects internally, allowing it to bend around corners and maintain brightness.
- Image Capture: The camera at the end of the endoscope captures the light reflected from the tissue, creating a clear image for the physician to analyze.
Advantages of Using Total Internal Reflection
- Minimally Invasive: Endoscopy provides a less invasive alternative to traditional surgical methods, leading to quicker recovery times.
- High-Quality Images: The use of optical fibers ensures high-resolution images, which are crucial for accurate diagnosis.
Conclusion
In summary, the effectiveness of endoscopic procedures is largely due to the principle of total internal reflection, allowing for effective light transmission and high-quality imaging within the human body. This technology has revolutionized diagnostic and surgical techniques in medicine.
