DP 10.1 [This question is pertinent to Sections 24-7 and 24-8 of the Textbook] A converging lens has a focal length of 20.0 cm. Answer the following two questions: (a) A real image is formed at a distance (from this lens) of 30.0 cm. What is the object distance? (b) A virtual image is located at a distance (from this lens) of -30.0 cm. What is the object distance? (Here, the image distance is negative because the image is virtual and is formed at the same side of the lens as the object. Besides, the object distance should be positive.) DP 10.2 [This question is pertinent to Sections 24-7 and 24-8 of the Textbook] An object is located 30.0 cm to the left of a diverging lens having a focal length f =-20.0 cm. (a) Determine the image distance. (Note that the image distance is negative because the image is virtual and is formed at the same side of the lens as the object.) (b) Determine the magnification of the image. Hint: Magnification is written as m =- nah, _ _d, It is your responsibility to interpret each variable and its sign convention correctly if you adopt this equation in your calculations
