A +2.5 cm focal length lens is used to project the image of a slide onto a screen. The lens is 3.0 m from the screen and the screen is 1.5 m wide and 0.5 m high. Part A) How far should the slide be from the lens to produce a crisp image on the screen? Part B) What are the dimensions of the slide (i.e. width and height) that would make an image that fills the entire screen?
An item is 20 em from a lens with a focal length of +12 em (convex lens). How far away must the screen be to produce a focused image, and what is the magnification of the image? Draw a rough picture of where the image is in relation to the object and the lens. 1. An item is 8 cm from a lens with a focal length of +12 cm (convex lens). Where does a focused image form? Can it...

A lens system consists of the two lenses shown in the diagram
below. The focal length of the first lens is 25 cm (you must decide
upon the correct sign) and the second lens has a focal length of 8
cm (again you must decide the sign). The lenses are spaced a
distance of 45 cm apart and the object is held a distance of 120 cm
to the left of the first lens.
c) If the original object is...
