1)Consider the following diagrams, where F represents the focalpoint of a concave lens. In these diagrams, the image formed by thelens is obtained using the ray tracing technique. Which diagramsare accurate?
2)If the focal length of the concave lens is -7.50
, at what distance 
from the lens should an object be placedso that its
image is formed 3.70 from the lens?3)What is the magnification
produced by the concave lens described in PartB?Homework Answers
2) f = -7.50 cm, di = -3.70 cm
1/do + 1/di = 1/f
∴do = (1/f - 1/di)-1 = 7.30cm
3) m = -di/do = 0.51

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.

A concave lens has a focal length of -36 cm. Find the image distance and magnification that results when an object is placed 19 cm in front of the lens. (Use the proper sign convention for both quantities.) When an object is located 61 cm to the left of a lens, the image is formed 25 cm to the right of the lens. What is the focal length of the lens? An object with a height of 2.22 cm is...

A biconvex lens sits between an object and a concave spherical mirror. The lens has a focal length f and the mirror has a radius of curvature of R. The object is a distance 2f from the lens and the distance from the lens to the mirror is 2f + R. The object is illuminated and light scattered from the object shines through the lens to the mirror, reflects, travels back through the lens, and forms a final image. (a)...
