Answer 1

Explanation:

..3 when the object is placed infront of concave lens in between

Answer 2

Answer:

i) At the focus of a convex lens

the size of the image is highly enlarged.

and position of the image is at infinity.

ii) Beyond the 2F point of a convex lens.

the size of image is diminished.

and the image formed between 2F And F .

iii)In front of a concave lens

case1

when object is at infinity

the size of image is highly diminished.

and the image formed at F2 (focus)

case2

when object is between infinity and optical centre

the size of image is diminished.

and the image formed between focus F2 and optical center
