Vibrations: Simple harmonic motion and damped S.H.M, and forced vibrations.
Waves: propagation of waves in a medium. The wave equation and its solution of a wave as a function of two variables: x=Acos(ωt-kz)
Superposition of waves: phasor method (Fresnel's construction), Interference of two waves of same frequency, Beats, and standing waves. Phase and group velocities.
Sound waves: Sound level and intensity. Doppler effect.
Reflection and refraction of light: Nature of light, index of refraction, optical path, Fermat's principle and the derivation of the laws of reflection and refraction. Total internal reflection.
Spherical interfaces: principle plane, optical axis, cardinal points, paraxial rays.
Optical components: flat and spherical mirrors, lenses, prisms, and aberration.
Optical instruments: eye and defects of vision, magnifier, microscope, and telescope,
