A periscope (see figure below) is useful for viewing objects that cannot be seen directly. It can be used in submarines and when watching golf matches or parades from behind a crowd of people. Suppose the object is a distance p1 from the upper mirror and the centers of the two flat mirrors are separated by a distance h. Pi (a) What is the distance of the final image from the lower mirror? (Use any variable or symbol stated above as necessary.) d = behind the lower mirror (b) Is the final image real or virtual? virtual real (c) Is it upright or inverted? inverted Oupright (d) What is its magnification?

The radius of curvature of a spherical concave mirror is 16.0 cm. Describe the image formed when a 20.0-cm-tall object is 11.0 cm from the mirror. What is the image distance ?A, measured in centimeters (cm)? ?A= ?    cm What is the image height ℎA, measured in centimeters (cm)? ℎA= ?    cm   Describe the image formed when a 20.0-cm-tall20.0-cm-tall object is 16.0 cm from the mirror. What is the image distance ?B, measured in centimeters (cm)? ?B= ?  cm What is the image height ℎB, measured in centimeters (cm)? ℎB= ?  cm   Describe the image formed when a 20.0-cm-tall object is 80.0 cm from the mirror.

Please help me with this question.

A man stands in front of a mirror as shown in the figure below. His eyes are 1.78 m above the floor, and the top of his head is 0.13 m higher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. top m bottom m How is the distance d from the top to the bottom of the mirror related to the man's height h? d =

An object is placed a distance do = 18.0 cm in front of a convex (negative) mirror with a focal length f= -9.0 cm. What is the image distance for the image formed by this mirror? d₁ = What is the magnification for this image? m= cm Is the image upright or inverted? O no image is formed O inverted O upright Is the image real or virtual? O real O virtual O no image is formed do

Part (a)  The object is placed at a distance in front of the mirror which is twice the focal length, i.e. do=2F. Enter an expression for the distance between the image and the mirror.   Part (b)  Which statement best indicates the position of the image?    Part (c)  The object remains at a distance in front of the mirror which is twice the focal length, i.e. do=2F. If the positive height of the object is ho, enter an expression for the magnitude of the image height, |hi|. Your expression will contain the object height.    Part (d)  Which statement best describes the image that is formed?    Part (e)  Which statement best describes the image that is formed?
