Question:
A thin convex lens of focal length 25 cm is cut into two pieces 0.5 cm above the principal axis. The top part is placed at (0,0) and an object placed at (–50 cm, 0). Find the coordinates of the image.
Solution:
1/v = 1/u + 1/f = 1/-50 + 1/25 = 1/50
v = 50 cm
Magnification is m = v/u = -50/50 = -1
Therefore, the coordinates of the image are (50 cm, -1 cm)
