5. An isоsceles prism with аn аpex аngle оf 280 has an index оf refraction of 1.51. Determine the minimum angle of deviation for this prism. 6. An object is located 210 cm to the left of a DCV with a 650 mm focal length. Determine: a) Image distance; b) Magnification c) Describe the image, d) Draw the ray tracing diagram for this problem. 7. A PCX has a focal length of 52 cm and an index of 1.47. The PCX is submerged in water (1.33). Determine the values for R1 and R2. Note: The convex surface is the 1st surface. 8. Determine the relative aperture for a 1.8” diameter lens, knowing that the focal length is 21.5 cm. What is the effect on the focal length if the relative aperture is increase for the same diameter lens? 9. An optical system consist of two optical elements: DCX and CV, each of focal length 150 mm. The system is used to form an image of an inverted object 3 cm high, 20 cm from the first element. The separation between the two elements is 90 cm. Determine: a) Image distance; b) Magnification c) Describe the image, d) Draw the ray tracing diagram for this problem. 11. A two-lens system is made up of a diverging lens followed by a converging lens, each of focal length 250 mm. The system is used to form an image of an object 95 mm high, standing erect, 720 mm from the first lens. The two lenses are separated by a distance of 80 cm. Describe the image formed by this system.
