You've been asked to set up a demonstration that uses a concave spherical mirror to form images under different conditions. You have a mirror, which has a radius of curvature of 60 cm. Looking at the size of the classroom, you decide that placing the object at distances of 90 cm and 20 cm from the mirror will make good examples. To verify this, you calculate, for each position, the location and magnification of the image, as well as whether it will be possible to project the image on a screen. Yu must solve this problem using a good diagram and geometry. It is not permissible to use the lens/mirror equation.

An optician is designing a contact lens. The material has is an index of refraction of 1.30. In order to yield the prescribed focal length, the optician specifies the following dimensions: inner radius of curvature = +2.46 cm outer radius of curvature = +2.02 cm where the inner radius of curvature describes the surface that touches the eye, and the outer radius of curvature describes the surface that first interacts with incoming light. What is the focal length of this contact lens (in cm)?
A plane mirror and a concave mirror (f = 7.50 cm) are facing each other and are separated by a distance of 17.0 cm. An object is placed between the mirrors and is 8.50 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. Find the location of the image that this light produces in the concave mirror. Specify this distance relative to the concave mirror. Number -10.6 Units cm C Object ◄► F

A convex lens has a radius of curvature of 20 cm. A 36-cm high object is placed 15 cm in front of the lens. Determine the location, nature, size, and orientation of the formed image.
The equation connecting s, p, and f for a simple lens can be employed for spherical mirrors, too. A concave mirror with a focal length of 5 cm forms an image of a small object placed 15 cm in front of the mirror. Where will this image be located? (For spherical mirrors, positive p means the image is on the same side of the mirror as the object.)
A small object is placed 25.0 cm to the left of a concave lens. A convex lens with a focal length of 12.0 cm is 30.0 cm to the right of the concave lens. The two-lens system forms a real inverted image 17.0 cm to the right of the convex lens. What is the focal length of the concave lens?
A tall tree is growing across a river from you. You would like to know the distance between yourself and the tree, as well as its height, but are unable to make the measurements directly. However, by using a mirror to form an image of the tree and then measuring the image distance and the image height, you can calculate the distance to the tree as well as its height. Suppose that this mirror produces an image of the sun, and the image is located 0.8278 m from the mirror. The same mirror is then used to produce an image of the tree. The image of the tree is 0.9219 m from the mirror. (a) How far away is the tree? (b) The image height of the tree has a magnitude of 0.13 m. How tall is the tree? (a) do = (b) ho= i i
A student notices that the image produced from a large concave mirror of a distant skyscraper (h = 106 m) is inverted and the magnitude of the height is |hi| = 1.16 m tall. The image is located d = 152 cm in front of the mirror. Numerically, what is the focal length of the mirror, f, in cm?
