An object is placed in front of a convex mirror. Draw the convex mirror (radius of curvature 5 15 cm) to scale, and place the object 25 cm in front of it. Make the object height 4 cm. Using a ray diagram, locate the image and measure its height. Now move the object closer to the mirror, so the object distance is 5 cm. Again, locate its image using a ray diagram. As the object moves closer to the mirror, (a) does the magnitude of the image distance become larger or smaller, and (b) does the magnitude of the image height become larger or smaller? (c) What is the ratio of the image height when the object distance is 5 cm to its height when the object distance is 25 cm? Give your answer to one signifi cant fi gure.

A dentist uses a mirror to examine a tooth that is 1.25 cm in front of the mirror. The image of the tooth is formed 14.0 cm behind the mirror. (a) Determine the mirror's radius of curvature. cm (b) Determine the magnification of the image. X

The side mirrors on cars are convex mirrors. If the side mirror on the driver side of your car has a focal length with a magnitude of 7.80 m and a truck is at a distance of 4.00 m from the mirror, determine the following. (a) image distance of the truck  ____ m(b) magnification for this object distance

An object is placed 30 cm in front of a converging mirror having a focal length of magnitude 20 cm. What is the image distance, in cm?  Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.   An object is placed 30 cm in front of a diverging mirror having a focal length of magnitude 20 cm.

A spherical mirror is to be used to form an image, five times as tall as an object, on a screen positioned 5.8 m from the mirror. (a) Describe the type of mirror required. The mirror is a Mirror Type-mirror and it has a focal length of (b) Where should the mirror be positioned relative to the object? m. Submit Answer The object should be m in front of the mirror.

A man standing 1.54 m in front of a shaving mirror produces an inverted image 14.0 cm in front of it. How close to the mirror should he stand if he wants to form an upright image of his chin that is twice the chin's actual size? cm

A concave mirror has a radius of curvature of 15 cm. An object is placed 7.5 cm from the mirror. Classify the image formed.? (ps the answer thats already on here is wrong)

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
