In the figure below, a diverging lens and concave spherical mirror are positioned along an optical axis, with an object half way between the two. The distance between the lens and mirror is d = 23.7 cm. The magnitude of the mirror's radius of curvature is 20.5 cm, and the lens has a focal length of flens = -18.4 cm. Lens Object Mirror (a) Considering only the light that leaves the object and travels first toward the mirror, locate the final image formed by this system. (Give the magnitude of the image distance in cm, and select its location with respect to the lens.) image distance cm image location to the right of the lens ✔ (b) Is this image real or virtual? O real O virtual (c) Is it upright or inverted? Ⓒupright O inverted (d) What is the overall magnification?

An object is placed  (3.80x10^1)  cm in front of a spherical mirror.--  An "upright" image is formed that is twice as tall as the object. You must do BOTH of the following.  FIRST determine the radius of curvature of the mirror in cm to 3 significant digits Be certain to include the appropriate "sign" for the focal length.

A shopper standing 1.54 m from a convex security mirror sees his image with a magnification of 0.234. Determine the following. (Indicate the directions with the signs of your answers.) (a) location of his image How is the magnification of a spherical mirror related to the object and image distance? m Is it in front of or behind the mirror? in front of the mirror behind the mirror (b) focal length of the mirror How is the focal length of a spherical mirror related to the object and image distance? m (c) radius of curvature of the mirror How is the radius of curvature of a spherical mirror related to the focal length? m

A concave spherical mirror has a radius of curvature of 20 cm. Give your answers with units. a) What is the image distance for an object at a distance of 30 cm from the mirror? Number Units b) Is this image real or virtual? O real O virtual c) What is the image distance for an object at a distance of 5 cm from the mirror? Number Units d) Is this image real or virtual? real O virtual

An object is placed 15 cm from a concave mirror with a radius curvature of 10 cm. Determine the distance image and the magnification of the object. Identify if it is a real object, what position, what side and the size of its magnification.

Where should an object be placed in front of a concave mirror so that it produces an image at the same location as the object? The radius of curvature of the mirror is rr.  What is the magnification of the image?

The mirror equation relates the object distance, d0, the image distance, di, and the focal length, f, of a mirror as1 / d0 + 1 / di = 1 / fWhile in other topics, distance and length are strictly non-negative, in optics we introduce the following sign conventions: Object distance is positive for a real object and negative for a virtual object. Image distance is positive for a real image and negative for a virtual image. Focal length is positive for a converging mirror and negative for a diverging mirror (a) Select the best choice to complete this statement. A real object placed in front of a converging mirror creates a real image  under all circumstances. under no circumstances. when the object is between the focal point and the mirror. when the object is farther than the focal length from the mirror. (b) Select the best choice to complete this statement. A real object placed in front of a diverging mirror creates a virtual image  under all circumstances. under no circumstances.…
