AB and CD, two spherical mirrors, form parts of a hollow spherical ball with its centre at O as shown in the diagram.

Question 1

AB and CD, two spherical mirrors, form parts of a hollow spherical ball with its centre at O as shown in the diagram. If arc AB =1/2 arc CD, what is the ratio of their focal length ? State which of the two mirrors will always form virtual image of an object placed in front of it and why.

Question 2

Focal length of both the mirrors will be the same 1:1

Mirror AB will always form a virtual image as it is a diverging/convex mirror.
