A concave mirror (R = 56.0 cm) is used to project atransparent slide onto a wall. The slide is located at a distanceof 40.0 cm from the mirror, and a smallflashlight shines light through the slide and onto the mirror. The setup is similar to that in the figure.
a) How far from the wall should the mirror belocated?
b) The height of the object on the slide is 1.50 cm. What is the height of the image?
c) How should the slide be oriented, so that the picture on thewall looks normal?
