How does an endoscope work?
उत्तर
- An endoscope is an instrument used by doctors which has a bundle of optical fibres that are used to see inside a patient’s body.
- Endoscopes work on the phenomenon of total internal reflection. The optical fibres are inserted into the body through mouth, nose or a special hole made in the body.
- Even operations could be carried out with the endoscope cable which has the necessary instruments attached at their ends.
