The correct Answer is:
To solve the question regarding the principle on which an endoscope operates, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Function of an Endoscope**: - An endoscope is a medical instrument used to view the internal parts of the body. It allows physicians to see areas that are otherwise difficult to access. 2. **Identifying the Optical Principle**: - The operation of an endoscope involves the transmission of light through flexible tubes, which are often made of optical fibers. 3. **Exploring the Properties of Light**: - Light can behave in several ways when it interacts with different materials. The relevant properties include reflection, refraction, total internal reflection, and dispersion. 4. **Focusing on Total Internal Reflection**: - The principle that allows the light to travel through the optical fibers in an endoscope is known as total internal reflection. This occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index at an angle greater than the critical angle. 5. **Conclusion**: - Therefore, the endoscope is based on the principle of **total internal reflection**. ### Final Answer: The endoscope is based on the principle of **total internal reflection**.
