Question
A point object 'O' is placed at a distance of 30 cm from a convex lens ( f=20 cm ) cut into two equal haves each of which is displaced by 0.05 cm as shown in figure. Find the position of image? If more than one image is formed, find their number and distance between them.
- 30 cm,2 images, 0.5 cm
- 40 cm,2 images, 0.3 cm
- 50 cm,2 images, 0.4 cm
- 60 cm,2 images, 0.3 cm
The correct answer is: 60 cm,2 images, 0.3 cm
