Two converging lenses with focal lengths of 45 cm and 22 cm are 12 cm apart. A 3.1-cm-tall object is 20 cm in front of the 45-cm-focal-length lens. Part A Calculate the distance between the final image and 22-cm-focal-length lens.

2. A Nikon 50mm camera lens is approximated as a cylinder with a diameter of 72mm and a length of 52.5mm. Determine the volume of the lens in cubic inches. Use correct significant figures in your answer. Assume 1cm = 10mm, 2.54cm = 1 in. Veylinder = ar2h

4. A convex (converging) lens produces a real, inverted image of an object that is magnified 2.20 times when the object is 37.0 cm from the lens. What is the focal length of the lens? cm

A small insect is placed 5.40 cm from a 6.00-cm-focal-length lens. a) Calculate the position of the image. Follow the sign conventions. Express your answer using two significant figures and include the appropriate units.   b) Calculate the angular magnification. Express your answer using two significant figures.

A concave lens has a focal length of -45 cm. a) Find the image distance that results when an object is placed 32 cm in front of the lens. b) Find the magnification that results when an object is placed 32 cm in front of the lens.

A student performs the lab as described. Leaving the object and 10 cm lens in place, a student places the 5 cm lens 35 cm away from the 10 cm lens.  a) Calculate the object distance for the 5 cm lens. b) Calculate the image distance from the 5 cm lens. c) Calculate the magnification of the 5 cm lens. d) Calculate the total magnification from both lenses. e) Calculate the expected final image height (from both lenses). f) Is the final image upright or inverted?

Light comes from an object and passes through a thin lens of unknown shape, creating an image shown in (Figure 1). a) If height h=3.00 mm and D=15.8cm what is the focal length of the lense in cm? b)what type of lens is it? c)what is the height of the image in mm? is the image real or virtual?

An image is located 346 mm behind a 204 mm focal length lens. A) Find the object distance. B) Find the magnification of the image. C) Is the image upright or inverted? factor of 4 or when you place it 8.0 cm behind a lens the

2. An object is placed 50.cm in front of a converging lens and then 15.5cm in front of a diverging lens. Both lenses have a focal length of 12.0cm. For both cases, find the image distance.

Problem 96. Indicate the single lens type (converging or diverging) and object position that will lead to the following kind of images. If no single lens system can produce the particular image indicate that this is so. A) real, upright, enlarged image. B) huge image at "infinity". C) real, enlarged, inverted image. D) tiny inverted image very near the focal point. E) real, reduced in size, inverted image. F) virtual, reduced in size, upright image. G) virtual, enlarged, upright image. H) real, inverted image that is the same size as the object. I) virtual, enlarged, inverted image. Problem 97. You are handed a converging lens and you have a ruler. Describe two different simple ways to determine the focal length of this lens. Each way should involve making only one measurement.
