MTEL Physics: Light, Mirrors & Lenses - Chapter Summary
Use our lessons to learn about light, including spectrum and color as well as the uses of mirrors and lenses as you prepare to take the MTEL Physics exam. These videos and quizzes will help you get ready for these types of questions:
- Looking at the origin of light, spectrum and color frequency
- Understanding reflection, including angle of incidence and curved surfaces
- Exploring the properties of color, including white light
- Defining and working with refraction and dispersion, including Snell's law
- Naming types and sources of light rays
- Using equations for questions on mirrors
- The functions of optical telescopes and compound microscopes
- Examining the lens of the eye and its function
These lessons are designed and taught by experts in the field who simplify and make the learning process enjoyable. Their use of examples help to clarify these concepts.
Objectives of the MTEL Physics: Light, Mirrors & Lenses Chapter
Massachusetts physics teachers must pass the MTEL Physics exam as a condition of their initial certification. The computer-administered exam is divided into seven subareas, and topics covered in the Light, Mirrors and Lenses chapter are in the exam's subarea on waves, sound and light, which accounts for 14% of the exam's scoring. Questions in this subarea are multiple-choice, like the questions in the quizzes that follow each of our video lessons. Practice taking the quizzes so that you'll be familiar with the examination's format.
1. 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.
2. Reflection: Angle of Incidence and Curved Surfaces
How do waves reflect off of surfaces? How do we account for the images that we see reflected in various objects? Discover the answers to these questions as we investigate the rays and angles defining the law of reflection.
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. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction
Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.
5. Light Rays: Definition, Types & Sources
This lesson will explain what light rays are, the main types of light rays, and how they can be simulated using lasers or beams of light. A short quiz will follow.
6. Using Equations to Answer Mirror Questions
After watching this lesson, you will be able to answer questions on mirrors, stating whether an image is real or virtual, upright or inverted, and larger or smaller. A short quiz will follow.
7. Optical Telescope: Facts & Overview
This lesson will explain what optical telescopes are, their history, how they work, and how they're used. We will also review the three types of telescopes, including the kinds of aberration (distortion) from which they can suffer. A short quiz will follow.
8. Lens of the Eye: Definition & Function
The lens of the eye focuses light and allows you to see. In this lesson, you will learn what the lens is made of and how it changes shape so that you can have clear vision.
9. Introduction to the Compound Microscope: Parts & Uses
The compound light microscope is a useful tool in any biology laboratory. In this lesson, you'll be introduced to the parts of a compound microscope, as well as understand the function of each of those parts.
