The lens and mirror in the figure below are separated by 1.00 m and have focal lengths of  +79.7 cm and −49.3 cm, respectively. If an object is placed 1.00 m to the left of the lens, where will the final image be located? q3 = ?cm   Determine the overall magnification ???

A contact lens is made of plastic with an index of refraction of 1.40. The lens has an outer radius of curvature of +1.92 cm and an inner radius of curvature of +2.47 cm. What is the focal length of the lens? cm

Chapter 34, Problem 041 A lens is made of a transparent material having an index of refraction of 1.70. One side of the lens is flat, and the other convex with a radius of curvature of 27.0 cm. (a) Find the focal length of the lens. (b) If an object is placed 51.0 cm in front of the lens, where will the image be located? (a) Number Units (b) Number Units

A student notices that the image produced from a large concave mirror of a distant skyscraper of height hs= 106 m is inverted and the magnitude of the height is |hiI = 1.46 m tall. The image is located di = 178 cm in front of the mirror. A)Write an expression for the distance between the mirror and the skyscraper, ds. B) What is the distance between the mirror and the skyscraper in meters? C) What is the focal length of the mirror, f, in centimeters?

A dental hygienist uses a small concave mirror to look at the back of a patient's tooth. If the mirror is 1.58 cm from the tooth and the magnification is 1.80, what is the mirror's focal length? (Include the sign of the value in your answer.) cm

q40 An object is 37.5 cm from a converging mirror (focal length = 13.0 cm). Determine the image magnification. Enter the numerical part of your answer to two significant figures. Hint: Remember that the sign of the magnification is significant.
