Note, value of unknown should be set to 0.0. Enter any 4 of 5 knowns, program calculates missing (=0) one. S[I] = 10.7. Image is real and to right of V. Type any key to exit. ||The input end of a wide glass (Ng=1.6) fiber is ground to a convex hemisphere of 1.5 cm radius. (a) If a point source is located 4 cm to the left of the hemisphere's vertex, where will its image be? Type comma key to see answer. Type (F2) to return to application file."
