Linear oscillators. Coupled oscillators and normal modes with mechanical and electromagnetic examples. Inertia, restoring force and damping. Driven systems and resonance. The continuum limit. Waves and wave equations. Dispersion relations. Phase. Interference and diffraction. Wave packets. Impedance, reflection, absorption and transmission. Polarization. Geometrical optics. Brief introduction to nonlinearity.


A student who has taken NS 214 would have an idea of linearity and superposition, would be able to recognize oscillators and wave systems in different contexts as analogues for the same basic physics, would be able to identify inertia and restoring force terms, derive normal modes, be familiar with concepts of damping, resonance, absorption transmission and reflection, dispersion relations and phase and group velocities.
She/he would be able to use these concepts in simple applications in electrical, mechanical and optical systems and to derive simple interference and diffraction patterns.
She /he would be able to visualize wave propagation and polarization. Mathematically the student will learn to use complex numbers, matrices and solve eigenvalue problems in this course, if she/he did not know these methods before.
