Image formation by concave mirror
Image formation by convex mirror
Lateral shift of a ray refracted through a parallel-sided slab
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)
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.
Tracing rays through (a) convex lens (b) concave lens.
Image formation by convex lens
Image formation by concave lens
A ray of light passing through a triangular glass prism.
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
