converging lenses are

A lens forms an image of an object. The object is 14.0 cm from the lens. The image is 17.0 cm from the lens on the same side as the object. (a) What is the focal length of the lens? Is the lens converging or diverging? (b) If the object is 9.20 mm tall, how tall is the image? Is it erect or inverted? (c) Draw a principal-ray diagram.

Two lenses, one converging of focal length 10.0 cm and one diverging of 5.0 cm, are placed 30.0cm apart. An object is placed 20.0 cm in front of the converging lens. Determine the location and magnification of the final image with respect to the original object.

A 5.87 mm high firefly sits on the axis of, and 12.5 cm in front of, the thin lens A, whose focal length is 6.05 cm. Behind lens A there is another thin lens, lens B, with a focal length of 23.7 cm. The two lenses share a common axis and are 60.7 cm apart. What is the height of this image? Express the answer as a positive number.

7. A lighted candle is placed 40.0 cm in front of a diverging lens. The light passes through the diverging lens and on to a converging lens (f = 10.0 cm) that is placed 9.00 cm from the diverging lens. The final image is real, inverted, and 35.0 cm beyond the converging lens. Find the focal length of the diverging lens. cm 0 ssf6 ssf60 ssf 60 ssf607 ssf60

A diverging lens has a focal length of magnitude 22.2cm.  Find the magnification for the object at distance 44.4 cm.  Find the magnification for the object at distance 22.2 cm. Find the magnification for the object at distance 11.1 cm.

When two lenses are used in combination, the first one forms an image that then serves as the object for the second lens. The magnification of the combination is the ratio of the height of the final image to the height of the object. A 1.20 cm-tall object is 60.0 cm to the left of a converging lens of focal length 40.0 cm. A second converging lens, this one having a focal length of 60.0 cm, is located 300 cm to the right of the first lens along the same optic axis.

Consider the optical system shown in the figure. The lens and mirror are separated by d = 1.00 m and have focal lengths of f₁ = +87.5 cm and f₂= = -53.4 cm, respectively. An object is placed p = 1.00 m to the left of the lens as shown. Lens LL -1.00 m Object distance location (a) What is the distance (in cm) and location of the final image formed by light that has gone through the lens twice? (Give the magnitude of the distance and select its location with respect to the lens.) ---Select--- -1.00 m- cm Mirror (b) Determine the overall magnification of the image. (c) State whether the image is upright or inverted. upright inverted
