An endoscope uses the principle of total internal refraction to provide high resolution images of internal organs like the colon and lungs. A. Describe how total internal reflection allows fiber optic cables to transmit images along curved paths with cable only a few millimeters thick. (4 pts) B. What is a 'critical angle'? (4 pts) C. The index of refraction of silica glass ranges from 1.40 to 1.55 . Find the speed of light and the critical angle in air for both of these values. ( 4 pts ) D. Calculate the new critical angle if the endoscope is submerged in water. (4 pt5) Please Answer ALL questions.
