What is the focal length of a mirror whos magnification is m = +1?
Asked by | 24th Jan, 2010, 12:10: PM
Expert Answer:
Magnification = Image height/Object height = -image distance/object distance.
Since magnification = +1
Image distance = -Object distance.
1/Focal Length = 1/Image distance + 1/Object distance.
1/Focal Length = 0
Focal Length = Infinity.
