PHYS 206 (3-0-3) Waves
Oscillations: Simple harmonic motion, application of S.H.M. and uniform circular motion,
combination of S.H.M., Lissajou’s figures, damped harmonic motion, forced harmonic motion a
nd resonance. Waves in Elastic Media: mechanical waves, types of waves, travelling waves,
wave speed in a stretched string, interference of waves, standing waves, power and intensity
in wave motion. Sound waves: audible, ultrasonic and infrasonic waves, propagation and
speed of longitudinal waves, travelling longitudinal waves, sound intensity and sound levels,
vibrating systems and sources of sounds, Doppler effect. The Electromagnetic Plane Wave:
Maxwell’s equations, a more general sinusoidal plane wave, types of polarization, natural light,
the recognition of a linearly light, polarization by reflection from a dielectric and Brewster angle,
Fresnel’s formulas, total internal reflection, reflection by a prism. Interference: Young’s double slits,
coherence, intensity of interfering waves, interference from thin films, Michelson’s interferometer.
Diffraction: diffraction from a single slit, diffraction from a double slit, multiple slits, diffraction
grating, resolved power of the grating. Heat and thermodynamics; the Celsius and Fahrenheit scales,
thermal expansion, quantity of heat, heat conduction, mechanical equivalent of heat, heat and energy,
first law of thermodynamics and applications.
