This in-depth study of the properties of light, sound and waves is presented in four programs. Each video includes a 15-question review and an extensive 30-page teachers guide with ten student masters.
The Nature of Light covers electromagnetic spectrum, wavelength, frequency, radio waves, infrared rays, visible spectrum, ultraviolet rays, x-rays, gamma rays, longitudinal wave, transverse wave, light-year, neon, photon and photoelectric effect.
Using Light covers regular and diffuse reflection, laws of reflection, focal point, diffraction, transparent, opaque, angle of inflection, plane, concave and convex mirrors, refraction, lasers, angle of refraction, and concave and convex lenses.
Sound covers sound waves, elasticity, density, hertz, frequency, pitch, ultrasonic, infrasonic, Doppler Effect, intensity, loudness, noise, timbre, interference and decibel.
Waves covers vibration, crest, trough, amplitude, period, medium, wavelength, frequency, reflection, refraction, rarefaction, diffraction, interference, and mechanical, electromagnetic, transverse, surface and longitudinal waves.
