1. Transparent and Opaque Materials in Electromagnetic Waves
What makes an object transparent or opaque? How does light pass through some objects and not others? And what about the other types of electromagnetic waves? We'll investigate all these questions in this lesson about the transparency and opacity of materials.
2. Translucent: Definition & Examples
In this lesson, we'll explore the meaning of the term translucent and discuss the properties of translucent materials and when and why using translucent materials may be desirable.
3. Color: White Light, Reflection & Absorption
What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.
4. How Light & Matter Interact
This lesson will go over the fundamental basic of how light and matter interact with one another. You'll learn about photons, excited atoms, binding energy, and energy levels.
5. Transmission of Light: Definition & Overview
This lesson will explain what is meant by 'transmission of light,' discuss the ways that light can be transmitted through a medium, and also explore how light is measured.
