4. Polystyrene with an index of refraction of 1.55 is used to create a thin lens. The front surface of the lens is concave with a 30.0 cm radius of curvature. The back surface is convex with a 26.0 cm radius of curvature. The image produced by the lens is 12.0 cm in front of the lens. a) What is the value for f, the focal length, of the lens in cm? b) Determine the magnification produced by the lens. c) A second lens with a focal length of +18.0 cm is placed 30.0 cm behind the first lens. Determine the location of the final image, i2 , produced by the two-lens system in centimeters.

MY QUESTION:

Refer back to problem # 4, part c, on the two-lens system. Draw a ray diagram using 3 rays from object # 2 – the object for lens 2 – to identify the final image produced by the two-lens system. Make your diagram neat and clearly labeled. [Given the size of the two lens system, I recommend making the drawing on a separate page with the page turned sideways in landscape orientation.]

1. [23/25 Points] DETAILS PREVIOUS ANSWERS A convex spherical mirror has a radius of curvature of magnitude 66.0 cm. A 13.0 cm tall bottle of Pellegrino Italian sparkling water is placed 30.0 cm in front of the mirror. a) Determine the focal length for this mirror in units of cm. -33 b) Determine the image distance, i, from the mirror to the image of the bottle in cm. -15.71 c) Determine the magnification produced by the mirror. 0.523 d) Identify the 3 main characteristics of the image produced by the mirror. Give your answer as a three (3) digit number using the codes given below: 1 = Real image 2 = Virtual image 3 = Inverted 4 = Not Inverted (upright) 5 = Magnified (bigger) 6 = De-magnified (smaller) For example, if you believe the image to be Real, and Virtual, and Inverted, then you would type for your answer the number: 123.
