Pendulo de mola
The nature, properties and behaviors of waves are discussed and illustrated; the unique
nature of a standing wave is introduced and explained.
The nature of sound as a longitudinal, mechanical pressure wave is explained and the
properties of sound are discussed. Wave principles of resonance and standing waves are
applied in an effort to analyze the physics of musical intruments.
The behavior of light waves is introduced and discussed; polarization, color,
diffraction and interference are introduced as supporting evidence of the wave nature of
light. Color perception is discussed in detail.
The ray nature of light is used to explain how light reflects off of planar and curved
surfaces to produce both real and virtual images; the nature of the images produced by
plane mirrors, concave mirrors, and convex mirrors is thoroughly illustrated.
The ray nature of light is used to explain how light refracts at planar and curved
surfaces; Snell's law and refraction principles are used to explain a variety of
real-world phenomena; refraction principles are combined with ray diagrams to explain why
lenses produce images of objects.
