A thin lens has a focal length of25.0 cm.(a) Find the location of the image formed by the lens when an object is placed at distance26.2 cmin front of the lens.(b)Describe the image (real/virtual, upright/inverted, enlarged/reduced). (c)Findthe location of the image formed by the lens when an object is placed at distance 24.0cm in front of the lens.(d) Describe the image (real/virtual, upright/inverted, enlarged/reduced).

1) Calculate the magnification of the 36-in refractor at Lick Observatory on Mount Hamilton near San Jose, California. The focal lenght of the objective lens is 17.37m, and the focal lenght of the eyepiece is 22 mm. (Express your answer to three significant figures.) 2) What is the significance of the negative sign in the magnification equation?       a) The image is inverted when viewed in the eyepiece.        b) The image is upright when viewed in the eyepiece.

A microscope has an eyepiece with a focal length of 18.0 mm, and an objective with a focal length of 8.00 mm. Thelenses are separated by 19.7 cm. A) If the final image is located infinitely far away, where is the object located? B) What is the total magnification?

An object is located 15.8 cm to the left of a diverging lens having a focal length  f = −36.2 cm. (a) Determine the location of the image. distance      cm location      ---Select--- to the right of the lens to the left of the lens (b) Determine the magnification of the image.(c) Construct a ray diagram for this arrangement.
