1. Spectroscopy: Definition and Types
In this video lesson, we will introduce and discuss different spectroscopic techniques used by scientists in an analytical lab. We will understand the importance of these techniques and show how they can be employed in identification and analysis.
2. The 7 Major Regions of the Electromagnetic Spectrum
This lesson will walk you through each of the major regions of the electromagnetic spectrum. Explore the unique characteristics of X-rays, microwaves, radio waves, UV rays, infrared, gamma rays, and of course, visible light.
3. Electromagnetic Waves: Definition, Sources & Properties
In this lesson, learn the basics of electromagnetic waves and how they make up the electromagnetic spectrum. We will explore the major trends and categories within the spectrum, as well as the various sources of electromagnetic waves.
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. The Nature of Light: Origin, Spectrum & Color Frequency
This lesson introduces the basics of visible light and color. Learn how the visible light spectrum is divided into the six color ranges. We'll also discuss why different people name colors in different ways.
6. Atomic Spectrum: Definition, Absorption & Emission
In this lesson, we'll discuss the meaning of the term 'atomic spectrum' and distinguish between the two main types of atomic spectra: absorption and emission spectra. We'll also describe how each forms.
7. Infrared Radiation: Definition, Uses & Effects
This lesson will explain what infrared radiation is and discuss a number of practical uses and effects of infrared, including its connection to climate change and the way the atmosphere responds to infrared waves. A short quiz will follow.
8. What is UV Radiation? - Definition, Types & Effects
It's summertime, and you're applying sunscreen to avoid sunburn. But did you wonder what sunscreen does and what it protects us from? In this lesson, we'll learn all about UV radiation and some of its effects.
9. How Photomultiplier Tubes & Array Detectors Work
In this lesson, we will learn about two ways to improve detection in spectroscopy. We will learn how photomultiplier tubes and how photodiode arrays help us maximize our signals and improve output. A short quiz will test our knowledge.
