A reflection is just what you think it is, a mirror image. So how do you reflect a figure on a graph? Just flip it over. The teacher illustrates how to select a line of reflection (the x-axis) and make the calculations to flip the figure.

A transformation is the process of changing the graph of a figure or a shape. The instructor introduces the four most common transformations: reflection, dilation, rotation, and translation. So watch as she draws the transformations on a...

There are many ways to transform geometric figures. This lesson will illustrate how to reflect figures over a line to get a mirror image of the figure. The teacher will draw three different reflections: one as reflected over the y-axis,...

We really only see objects that emit light, either on their own or by reflecting light from another source. Past misconceptions of light are illustrated, and current understandings of light illuminated. This could be used as an...

Perform a reflection of a figure over the y-axis. This seems pretty straightforward. But also learn how to use the coordinates to reflect a figure.

Perform a reflection of a figure over the x-axis. This seems pretty straightforward. But also learn how to use the coordinates to reflect a figure.

Intended for learners with a solid understanding of algebra, physics, and scientific language, this clip describes the differences and functions of spherical and parabolic mirrors. This clip is not so much about telescopes but about...

Reflect on reflections by viewing this video. Looking in his bathroom mirror, the videographer explains that anything smooth can act as a mirror. He also introduces a curved mirror and demonstrates how the image differs depending on your...

It's not just movie magic - invisibility cloaks could be feasible, just by manipulating the crazy ways that light bounces, bends, and mixes! Prashanth and Maria take you behind the physics of light and how an invisible cloak could...

A good explanation of what happens when a crest or a trough wave hits a fixed or a closed end. Includes a simple but excellent demonstration of how this works. [3:40]

This video segment adapted from Shedding Light on Science demonstrates the law of reflection, showing how light energy is reflected off both smooth and rough surfaces at predictable angles. Includes background reading material and...

Mister Chris sings a song that honors the passing day and all we've experienced. We express being thankful for the variety of different feelings we felt throughout the day and get ready for the sun to set. This activity invites...

Penny and the KidVision VPK Kids visit an animal shelter. They learn the rules for petting a puppy, watch the vet give the puppy a checkup, see the relationship of the puppy's body parts to their own, and exercise outside with the puppy....

Students experiment with reflecting light using mirrors and learn about light intensity. [11:47]

Remember Sol, the closest star to Earth? We like to call it the Sun and we haven't talked about it in a little while. One interesting thing about the energy we get from the sun is that it's not absorbed the same way by different...

Planet Nutshell Math Shorts provide animated videos that explain various math topics. On this site students learn about reflections.

Demonstrates how to reflect points across the x- or y- axis in a coordinate grid. [3:35]

Transformations allow you to change or move a figure. Learn about all the different kinds of transformations by watching this tutorial. [4:18]

Learn how reflection occurs with a convex parabolic mirrors in this video lecture. Understand how the light reflects at the focus point and produces a smaller virtual image. [5:59]

This video tutorial demonstrates how to reflect a function across the x-axis and y-axis on a coordinate plane. It includes a detailed example.

Determine from an equation if it has been reflected on an axis then graph the equation and reflection in this video tutorial. [9:13] Assess learning with a quiz.

In this video tutorial, determine the line of symmetry with geometric objects and take a quiz to assess learning. [4:32]
