Shaving/makeup mirrors typically have one flat and one concave (magnifying) surface. You find that you can project a magnified image of a lightbulb onto the wall of your bathroom if you hold the mirror 2.0 m from the bulb and 3.7 m from the wall.
a) What is the magnification of the image?
b) Is the image erect or inverted?
c) What is the focal length of the mirror?
m = - di/do ?
1/di +1/di = 1/f
