When the rays are refracted they are bent towards the normal so that those that were near the top of the image come out near the bottom and vice versa.
Convex lens give a virtual & diminished image while concave lens give inverted virtual in rare case & magnified image.
we do get inverted image at the ratina. But this inverted image itself is being treated as errected by our mind.
yes
Whenever a real image is formed by a real object,the image is always inverted. for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
our optic nerves invert the image and our brain reads it
You need to draw a convex mirror. If you add lines normal to its surface you will see that the focal point is behind the mirror. The image is not inverted.
the image will be Unreal. Concave mirrors form a real and inverted image where in tn convex mirrors the images are unreal.
Convex lens is a converging lens It makes the image real and inverted whereas concave lens is a diverging lens it makes the image virtual and erect.
Function of Convex lens: Convex lens causes parallel rays of light to converge after refraction. Also the following can also be considered as the functions of convex lens: 1.when the object is at infinity, convex lens forms the image at focus which is real and inverted. 2.when the object is beyond 2F, image is formed between F and 2F which is real, inverted and diminished. 3.when the object is at 2F ,image is formed at 2F,which is real , inverted and of same size. 4.when the object is between F and 2F, image is formed beyond 2F which is real,inverted and magnified. 5.when the object is at F,image is at infinity which is real inverted and very much magnified. 6.when the object is between F and C, image is formed beyond 2F and behind the object which is virtual, erect and magnified.

For a convex lens, if you trace out the path of the rays as they are refracted through the lens, you'll see that the inverted image gets reversed horizontally as well as vertically (in other words, the "inverted" image is really a 180 degree rotation about the axis through the center of the lens).
