The Thin Film Interference Video Tutorial describes what thin film interference is and explains how the wave model of light is used to explain the phenomenon. Numerous examples, illustrations, and animations assist in the explanations.

The Polarized Light and Polaroid Filters Video Tutorial explains what polarized light is and how it is different than unpolarized light. The manner is which a Polaroid filter polarizes light waves is described. And the role of sunglasses in blocking the glare caused by polarized light is discussed. Numerous examples, illustrations, and demonstrations assist in the explanations.

The Electromagnetic and Visible Light Spectrum Video Tutorial describes electromagnetic waves and the EM spectrum, including the patterns in wavelength, frequency, and energy. The visible light spectrum is also discussed. Numerous examples, illustrations, and animations assist in the explanations.

The Eye And Color Video Tutorial describes the wavelength sensitivity of the three color receptors on the eye's retina and discusses how the incident-absorbed-reflected model can be used to explain how the eye-brain system perceives color in objects. Numerous examples, illustrations, and animations assist in the explanations.

The Color Addition Video Tutorial explains the physics of color and color vision. Using the incident-absorbed-reflected model, Mr. H explains how our eyes perceive color. Primary colors of light are defined and identified and the manner in which they add together to form secondary colors and the host of other colors is discussed.

The Color Subtraction Video Tutorial explains the interaction between light and the surface upon which it lands, with the interest of explaining why objects appear the color that they appear. Principles of color subtraction are described and applied to numerous situations.

The Pigments and Color Subtraction Video Tutorial explains what a pigment is and how it affects the color appearance of an object. The effect of combinations of pigments is discussed and the application of pigments to the world of color printing is explained. Numerous examples and illustrations give impact to the lesson.

The Filters and Color Subtraction Video Tutorial explains the interaction between visible light and color filters using the incident-absorbed-transmitted model. Numerous examples are done to illustrate the use of the model in predicting the color appearance of objects when viewed through a color filter.

The Anatomy of Two Point Source Interference Patterns Video Tutorial discusses the formation of antinodal and nodal lines on a two-point source interference pattern. Attention is given to the terminology associated with the patterns. Numerous examples, illustrations, and animations assist in the explanations.

The Path Difference and Wavelength Video Tutorial develops the mathematical logic by which the path difference for two waves meeting up at an anti-nodal or nodal line is related to the wavelength. Numerous examples, illustrations, and animations assist in the explanations.
