does anyone know how to do part B,C and C to this problem?anythingwould help. A concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens. If the focal length of the concave lens is -7.50 cm, at what distance d0 from the lens should an object be placed so that its image is formed 3.70 cm from the lens? Express your answer in centimeters. What is the magnification m produced by the concave lens described in Part B? Express your answer numerically to two significant figures. Where should the object be moved to have a larger magnification? The object should be moved closer to the lens. The object should be moved farther from the lens. The object should be moved to the focal point of the lens. The object should not be moved closer to the lens than the focal point.

A zoom lens system is a combination of lenses that produces a variable magnification of a fixed object as it maintains a fixed image position. The magnification is varied by moving one or more lenses along the axis. Multiple lenses are used in practice, but the effect of zooming in on an object can be demonstrated with a simple two-lens system. An object, two converging lenses, and a screen are mounted on an optical bench. Lens 1, which is to the right of the object, has a focal length of f₁ of 5.00 cm, and lens 2, which is to the right of the first lens, has a focal length of f₂ of 10.0 cm. The screen is to the right of lens 2. Initially, an object is situated at a distance of 7.50 cm to the left of lens 1, and the image formed on the screen has a magnification of +1.00.

(a) Find the distance between the object and the screen.

(b) Both lenses are now moved along their common axis while the object and the screen maintain fixed positions until the image formed on the screen has a magnification of +3.00. Find the displacement of each lens from its initial position in part (a).

(c) Can the lenses be displaced in more than one way?
