Lateral shift of a ray refracted through a parallel-sided slab
4
Refraction and internal reflection of rays from a point A in the denser medium (water) incident at different angles at the interface with a rarer medium (air)
5
a) The position of object, and the image formed by a double convex lens,
b) Refraction at the first spherical surface and
c) Refraction at the second spherical surface.

Image formation by concave lens
9
A ray of light passing through a triangular glass prism.
10
A simple microscope;
(a) the magnifying lens is located such that the image is at the near point,
(b) the object near the focal point of the lens; the image is far off but closer than infinity
