PHY102 : Waves and matter

PHY 102 : Waves and Matter

This is the first undergraduate course in wave phenomena and properties of matter.

This course will cover the following topics :

Oscillations and waves in one and many dimensions.
Damped and driven oscillations. Resonances.
Oscillations of continuous string and Fourier analysis.
Travelling waves, pulses and wave packets,
phase and group velocity, reflection, refraction and transmission.
Sound waves, speed of sound.
Properties of deformable media, Hooke's law, stress and strain.
Torsion and bending of rods, deflections of rods.
