6. An object is placed 20.0 cm in front of a converging lens with a focal length of 15.0 cm. This lens is 40.0 cm in front of a concave spherical mirror with a focal length of 30.0 cm. Consider the light from the object going through the lens, reflecting off of the mirror, and then going back through the lens, after which the final image is produced. Where is the final image produced relative to the lens, and what is its a) magnification, orientation, and image type?

8. A convex mirror (f₁ = -5.60 cm) and a concave mirror (f₂ = 9.00 cm) are facing each other and are separated by a distance of 15.0 cm. An object is placed between the mirrors and is 7.5 cm from each mirror. Consider the light from the object that reflects first from the convex mirror and then from the concave mirror. What is the distance of the image (d₁2) produced by the concave mirror? cm 285 jeh20 285 jeh285 jch285 jch285 j

Spherical Mirrors: An object is placed 50 cm in front of a concave mirror with a focal length of 25 cm. What is the magnification produced by the mirror? +1.0 +1.5 O-1.0 -2.0 -0.50

You use a lens to form an image. The object is 50 cm from the lens and the image is formed at a position of -14 cm. What is the focal length of your lens? f = cm What is the magnification of the lens? m = Is the image formed real or virtual? --- Is the image upright or inverted? Are you using a converging lens or a diverging lens?

5. Consider a converging lens that has a focal length (f). Which one of these is correct about the image when the object is placed in front of the lens at a distance of (3f)? The image is real, inverted, and diminished The image is real, erect, and diminished The image is real, erect, and magnified The image is virtual, inverted, and magnified The image is virtual, inverted, and diminished The image is virtual, erect, and has the same size as the object A nearsighted man uses his ideally prescribed eyeglasses that have a refractive power of -3.00 diopters. He would like a prescription for contact lenses. What is the correct contact lens prescription if he normally wears his eyeglasses a distance of 2.1 cm from his eyes? diopters

Create a ray diagram for eyeglasses that contain a diverging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm. What type of vision are they used to correct? Give both names. How do they do this? Explain.

10. A 1.1 cm tall object is placed 5 cm away from a mirror with focal length 16 cm. Calculate the height of the image. (Give your answer in centimeters but don't include the units.) MacBook D00 F2 F3 F4 F5 F6 F7 F8 @ & 4 5 6 7 8 W T Y K.

8. On one side of a converging lens of focal length 20.9 cm, you position an object of height 3.48 cm somewhere along the principal axis. The resultant image has a height of 8.00 cm. How far from the lens is the object located?     30.0 cm   12.0 cm   42.0 cm   21.0 cm

The projection lens in a certain slide projector is a single thin lens. A slide 24.5 mm high is to be projected so that its image fills a screen 1.77 m high. The slide-to-screen distance is 2.93 m. (a) Determine the focal length of the projection lens. mm (b) How far from the slide should the lens of the projector be placed to form the image on the screen? mm

8. On one side of a converging lens of focal length 59.1 cm, you position an object of height 3.02 cm somewhere along the principal axis. The resultant image has a height of 15.10 cm. How far from the lens is the object located?     70.9 cm     28.4 cm     92.2 cm     42.5 cm
