Answer 1

Answer:

a ) Concave Lens

b ) Covenx lens

Explanation:

Concave Lens :

In case of the concave lens, we always get -

• An inverted image smaller than the object .
• erect images
• diminished images
• virtual images.

Here if the object is very far away, the images formed by lenses will be all the more diminished.

Object location: Image location

Beyond infinity and 0: Between F1 and Optical centre

Infinity: At F2

Convex Lens :

• Erected image forms smaller than the object .

Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller.
