A spherical mirror is to be used to form a real image of an object that is located 5 meters from the object. The image will be 5 times larger than the original object (M=-s'/s= -5).
a) What type of mirror needs to be used?
b) What is s, the distance between the object and the mirror?
c) What is the radius of curvature of the mirror?
