Convex lenses are image forming; When an object is placed at.

When an object is placed at a defined distance from the concave lens. a virtual image is formed between the pole and the focus of the convex lens. The lens formula is expressed as follows:

(a) anywhere between optical centre and. No. the image formed by a concave lens.

#### (Ii) Is Always Virtual. Erect And Diminished In Size.

$$\frac{1}{f}=\frac{1}{v}+\frac{1}{u}$$ where f is the focal length. v is the distance of the image from the centre and u is the distance of the object from the centre. Image formation by convex mirror. The image formed in a convex mirror is always virtual and erect. whatever be the position of the object.

#### Give The Position. Size And Nature Of Image Formed By A Concave Lens When The Object Is Placed:

An image formed by the concave lens can be real and inverted as well as virtual and erect. It is highly diminished . virtual and erect. Hence finally. v = − 30 c m . | h o | = 2 c m and the image is real and inverted.

#### And It Is Very Very Small.

This is also because the image is formed at the same side of the mirror with the object. Give the position. size and nature of image formed by a concave lens when the object is placed : A convex lens is put 10 cm from a light source and it makes a sharp image on a screen. kept 10 cm from the lens.

#### So. The Position Of The Object Doesn’t Matter In The Case Of The Image Formed By A Concave Lens.

When an object is placed at. This holds good for all positions of the object. As a convex lens forms different types of images depending on the position of object. similarly a concave lens also forms different types of images when the object is placed at 1.

#### The Size Of The Image Formed Is Much Smaller Than The Object.

The nature of it depends on the position of the object. if it is placed very close to the mirror. the image would be virtual and erect. When an object is placed at infinity. a virtual image is formed at the focus. When the object is placed between the infinity and the optical center o of the lens. the image formed by the concave lens will be between the first focus. f1 and the optical center o.
