Question

3-11. A concave mirror forms an image on a screen twice as large as the object. Both object
and screen are then moved to produce an image on the screen that is three times the
size of the object. If the screen is moved 75 cm in the process, how far is the object
moved? What is the focal length of the mirror?

A concave mirror produces a larger, inverted, real image. Which is true regarding the image distance? It is between the radius of curvature and the focal point. It is closer to the mirror than the focal point. It is at the focal point. It is farther away than the radius of curvature.
You are looking for a mirror that will enable you to see a 3.3-times magnified virtual image of an object that is placed 4.9 cm from the mirror’s vertex. What should the mirror’s radius of curvature be, in centimeters?
A student notices that the image produced from a large concave mirror of a distant skyscraper of height hs= 106 m is inverted and the magnitude of the height is |hiI = 1.46 m tall. The image is located di = 178 cm in front of the mirror. A)Write an expression for the distance between the mirror and the skyscraper, ds. B) What is the distance between the mirror and the skyscraper in meters? C) What is the focal length of the mirror, f, in centimeters?
Problem 6: You are looking for a mirror that will enable you to see a 3.4-times magnified virtual image of an object that is placed 4.2 cm from the mirror’s vertex. A concave mirror will be used Part (b) What should the mirror’s radius of curvature be, in centimeters?
You have a concave spherical mirror (the same holds if you had a convex mirror) If the value of q(the distance from the image to the mirror along the principal axis of the mirror) is 1.45m and the distance of p (the distance from the object to the mirror along the principal axis of the mirror) is 4.11m, what is the focal length of the mirror? The magnification equation and the sign convention for q imply that real images of real objects are always inverted (if both p and q are positive, m is negative); virtual images of real objects are always upright (if p is positive and q is negative, m is positive). Keeping the signs of p and q straight in your mind is the most challenging aspect of mirrors (and lenses). Fortunately, table 23.2 summarizes when p and q are positive and when they are negative.
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?
