is it true that a real image is always inverted while a virtual one is always upright? i think it is.
and what are the properties of an object placed at f? it can be virtual or real, but other than that, is there any other properties?
for convex lens in O levels, yes

Thanks!
By the way, i chanced upon a statement which says,"a piece of material is given and it is semi-circle in shape. when light is shone PERPENDICULARLY at the material, light is being refracted".
how can the light ray be refracted when shone pependicularly? I thought it should go through material undeviated?
post the whole thing. with the picture

Refracted when coming out on the other side?
Take note that the light cannot be shone perpendicular to the material at the midpoint of the semi-circle.

Just like you stated.
If it is real, then it is inverted. Vice-versa.
