Answer 1

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1 , its image is formed beyond 2F

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1 , its image is formed beyond 2F 2

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1 , its image is formed beyond 2F 2

The required diagram is shown in the figure. When an object is placed in front of the convex lens, i.e., between 2F 1 and F 1 , its image is formed beyond 2F 2 on the other side of the lens. The image is real, inverted and enlarged.
