The lens Maker's formula is given by
At a convex surface, light rays travelling from a rarer medium to denser medium bend towards the normal, converging to a point. This makes convex lenses focus light to form real images.
At a concave surface, light rays travelling from a rarer to a denser medium bend towards the normal, diverging outward. This makes concave lenses spread out light rays, creating virtual images.
The critical angle is the angle of incidence in a denser medium beyond which light undergoes total internal reflection.
Hence, A-(IV), B-(III), C-(II), D-(I).
