An object with a height of 4.48mm is a distance of 25.7 cm to the left of lens f1 with a focal length of -24.7cm. At a distance of 79 cmto the right of lens fi is lens f2 with a focal length of 33cm. Determine the magnitude of the height, hi, of the final image (in mm). You Answered 0.123 Correct Answer 1.2365 margin of error +/- 1%

A converging lens made of crown glass has a focal length of 15.0 cm when used in air. If the lens is immersed in water, what is its focal length? (a) negative (b) less than 15.0 cm (c) equal to 15.0 cm (d) greater than 15.0 cm (e) none of those answers

A camera lens used for taking close-up photographs has a focal length of 22.0 mm. The farthest it can be placed from the film is 33.0 mm. (a) What is the closest object that can be photographed? (b) What is the magnification of this closest object?

(a) Where does an object need to be placed relative to a microscope for its 0.500 cm focal leng1h objective to produce a magnification of 400? (b) Where should the 5.00 cm focal length eyepiece be placed to produce a further fourfold (4.00) magnification?

. If the mirror described in the previous problem is used to form an image of the same object now located 16 cm in front of the mirror, what would the new image position be? Assuming that the magnification equations developed for lenses also apply to mirrors, describe the image (size and orientation) thus formed.

The figure shows an object and its image formed by a thin lens. Assume that d1 = 0.308 m, d2 = 0.252 m, and h = 7.50E-2 m. What is the image height (in m; answer sign and magnitude)?   give answer in 3 sig figs and scienttifc notation
