If an object 15 cm tall is placed 30 cm in front of the mirror, calculate the magnification of the image formed.0.60.50.40.3       In a homemade projector, a concave mirror with a focal length of 8 cm is used to project an image onto a screen. If an object with a height of 5 cm is positioned 12 cm in front of the concave mirror, at what distance should the screen be located to capture a sharp image? Additionally, calculate the height of the image formed on the screen.12 cm and 12 cm respectively12 cm and 10 cm respectively24 cm and 12 cm respectively24 cm and 10 cm respectively       A makeup artist uses a concave mirror with a focal length of 18 cm to get a closer view of a client's face. If the client's face is positioned 12 cm from the mirror, where will the image of the face appear and what will be the nature of the image?18 cm; virtual, erect and magnified18 cm; real, erect and diminished36 cm; real, upright and diminished36 cm; virtual, upright and magnified

A virtual image of a real object formed in the mirror is observed to be reduce to one-third of the size of the object. If the focal length of the mirror is 25 cm, then the object distance isOnly one correct answerA.50 cmB.25 cmC.75 cmD.40 cm

If the object is moved towards the plane mirror the final distance between the image and the object is 40 cm and if the final image is displaced by 10 cm from initial image what is the initial distance of the object from the mirror?10 cm30 cm20 cm40 cm

If the distance between object and its two times magnified virtual image produced by a curved mirror is 15 cm, the focal length of the mirror must be :
