1. Image Formation by Mirrors:
An object is placed at a distance of 100 cm in front of a convex mirror. A plane mirror is placed at a distance of 40 cm from the convex mirror on the same side as the object. Find the focal length of the convex mirror if the images formed by the two mirrors coincide.

An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...

The magnification factor m= An object is placed in front of a concave mirror with a focal length of 10 cm . The image formed is at a distance of 20 cm on the same side of the mirror. The magnification factor m= An object is placed in front...
If when an object is placed 12.0 cm in front of a mirror the image is located 20.7 cm behind the mirror, determine the following. (a) the focal length of the mirror What is the relationship between the focal length, image distance, and object distance for a spherical mirror? What is the sign associated with the image distance of an image behind the mirror? cm (b) if the mirror is concave or convex concave convex
An object is placed to the left of a convex mirror, such that the object-to-image distance is 88 cm. Find the focal length of the mirror, if the image is 20 cm from the mirror.
1. The image of an object is 11.1 cm behind a convex mirror when the object is far from the mirror. Determine the absolute value of the distance from the mirror to the image when the object is placed 2.5 cm in front of the mirror. ______ cm 2. If when an object is placed 13.5 cm in front of a mirror the image is located 21.7 cm behind the mirror, determine the following. The focal length of the mirror....
Could you please guys answer these problems as soon as possible. I need to submit on friday thank you in advance 1. An object is placed at a certain distance s of a mirror of focal length 20.0 com and an erect image 4 times the size of the object is formed. Where is the object located relative to the mirror? 2. An object is placed 5.00 m from a wall. You are to use a mirror to project an...
5. An object 3 cm high is placed 20 cm from a convex mirror having a focal length of 8 cm. Find the position of the image and its magnification. Draw a schematic ray diagram. 6. What are two major problems in using spherical mirrors and lenses for image formation?
An object is placed 33.5 cm in front of a convex mirror. If the focal length of the mirror is −19.5 cm, find the distance between the object and the final image.
Example 7 (Concave Mirrors) A 10 (cm) tall object is placed in front of a concave mirror with diameter 40 (cm) In four cases (case 1 to case 4) of placing the object at case 5 (cm), 10 (cm), 15 (cm) and 25 (m). Describe the image as following: 1- Position of the image in respect to mirror (the distance of image from mirror) 2- What is the height of image? Is the object magnified or reduced? 3- Is the...
