Ray Optics and Optical
Instruments
Ray Optics: Reflection of light, spherical mirrors, mirror formula, refraction
of light, total internal reflection and optical fibers, refraction at spherical
surfaces, lenses, thin lens formula, lens maker’s formula, magnification,
power of a lens, combination of thin lenses in contact, refraction of light
through a prism.
Optical instruments: Microscopes and astronomical telescopes (reflecting
and refracting) and their magnifying powers.
