Description

Overview of the essential ideas for this topic.

9.1: The solution of the harmonic oscillator can be framed around the variation of kinetic and potential energy in the system.

9.2: Single-slit diffraction occurs when a wave is incident upon a slit of approximately the same size as the wavelength.

9.3: Interference patterns from multiple slits and thin films produce accurately repeatable patterns.

9.4:  Resolution places an absolute limit on the extent to which an optical or other system can separate images of objects.

9.5: The Doppler effect describes the phenomenon of wavelength/frequency shift when relative motion occurs.
