A 3.0-cm-tall domino is located 100 cm from a concave spherical mirror of R = 30 cm. Locate the position of the image and find the magnification.
A woman 168 cm tall stands in front of a plane mirror attracted to a vertical wall. What is the minimum length that the mirror must have for the woman to see her entire height?
This problem deals with lenses, please explain using equations, and ray diagrams. A real object is at the zero end of the meter stick. A large concave mirror at the 100-cm end of a meter stick forms an image of the object at the 70-cm position. A small convex mirror placed at the 20-cm position forms a final image at the 10-c
A candle is placed in 15.0 cm in front of a convex mirror. When the convex mirror is replaced by a plane mirror, the image moves back 7.00 cm (further away from the mirror). Find the focal length of the convex mirror.
