Wave Properties and Motion Concepts

The video provides an introduction to light and physical optics, reviewing wave theory and types of waves such as transverse and longitudinal. It covers wave properties like period, frequency, amplitude, and phase shift, and introduces simple harmonic motion. The video includes example calculations of wave properties and concludes with a transition to electromagnetic waves.
