Q. If the reflecting surface is curved outwards it is a convex mirror.

Q. Which mirror has its reflecting surface curved inwards?

Q. The surface of the spoon which is curved inwards can be approximated to be ($a$) .......... mirror and the surface of the spoon which is bulged outwards can be approximated to ($b$) ......... mirror.

Q. A reflecting surface is curved inwards. Now, the mirror formed is :

Q. A reflecting surface is curved outwards. The mirror formed will be :
