Question

Equipment Inside of Submarine Air Water Your eye Port 1.) You look out the window of a small submersible. The window is spherically shaped with center of curvature C and radius of curvature r. Both the window and the ocean water have the same index of refraction, nw. You are located at the point labeled on the diagram above and there is some equipment behind you. You can see through the window, but it also acts as a mirror in which you can see the equipment behind you. a. What is the focal length of the mirror? b. Sketch a ray diagram for the image of the equipment formed by the mirror effect. Equipment c. is the image formed by the mirror effect upright or inverted? Real or virtual? And larger or smaller than the equipment? d. You see a seahorse outside the window. Sketch the ray diagram for the position of the image formed by the seahorse. Water 1 e. Is the image of the seahorse upright or inverted? Real or virtual? And larger or smaller than the equipment?

Answer 1

equipment placede placede at distance u at distance a from window and -14 is the distance of image the focal length. - I - b f= (u tv) Luv b. a'o' is image produce by minor effect. B! B C A' C.) image produced by missor effect is real, invented and small in size, di if it far away from Window A Bl B A! This image in real, to inverted, in size small

to Window is too near If it f this image is virtual , erect, larger in size Both type of image are possible depends on object distance
