This video explains the technical process behind the formation of images in plane mirrors, and justifies the characteristics of those images. It covers the laws of reflection, the formation of point images, and the fact that the image in...

This video explains the science behind reflection in plane mirrors, including the formation of virtual and real images, lateral inversion, and the properties of upright and erect images. It also includes an activity to identify letters...

This video focuses on where and why plane mirrors are used and image formation. Students will come to understand that plane mirrors form virtual images, and that that image is the same size as the object it reflects and is as far behind...

How many times do you look in a mirror every day? Have you ever stopped to wonder how they actually work? Mirrors do strange things to our world, seemingly flipping everything so that what was right is left and what was left is right....

In this video Paul Andersen explains how ray diagrams can be used to determine the size and location of a reflected image. Ray diagrams for plane, concave, and convex mirrors are included.

In this video lesson we will learn how to reflect images in the coordinate plane over the x and y axis. We will first identify the line of reflection given in the instructions. We will then determine the distance the original point is...

Pupil outcome: I can describe and explain the properties of reflections in a plane mirror, and draw diagrams to show how reflections form. Key learning points: - Reflections are the same size as the object, upright, and the same distance...

Optical isomerism occurs in molecules that are chiral, meaning they cannot be superimposed on their mirror images. These isomers, known as enantiomers, differ in their optical activity—they rotate plane-polarized light in opposite...

How are the contents of animals organized? How does this differ from animal to animal? Are all animals symmetrical, and in the same ways? Just a bit more information to get through before diving into all the animal phyla, I promise!

This video lesson is the second video in the playlist or unit of videos on transformations. The first video explained translations. This video explains reflections as the mathematical flip over the line of reflection. Real world...

In optics, the point at which rays of light converge after refraction or reflection, and so the point at which a sharp image will be produced. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning...

Biphenyls are compounds consisting of two benzene rings connected by a single bond. In certain biphenyls, bulky substituents on the ortho positions of the rings can prevent free rotation around the bond, locking the rings in different...

In this video, you will learn how to find the axis of symmetry and vertex of a quadratic function by solving part of the quadratic formula. The axis of symmetry is a vertical line that divides the graph into two symmetrical parts, while...

Lactic acid (2-hydroxypropanoic acid) is a classic example of a chiral molecule. It contains a chiral center at the second carbon atom, bonded to a hydroxyl group (-OH), a hydrogen atom, a carboxyl group (-COOH), and a methyl group...

The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify molecules as chiral or achiral. And as always, we’ll be doing a...

Allenes are compounds with a unique structure characterized by two adjacent double bonds (C=C=C). Despite having no traditional chiral centers, certain substituted allenes can exhibit chirality and optical activity due to their rigid,...

Symmetry and optical activity are intricately linked in organic molecules. A molecule is optically active if it can rotate the plane of polarized light. Optical activity arises from the molecule’s lack of symmetry—specifically, its...

For a molecule to exhibit optical activity, it must be chiral, meaning it has no internal plane of symmetry. Additionally, the solution or compound should not contain equal amounts of enantiomers (racemic mixture), as these cancel out...

Stereoisomerism refers to isomers that have the same molecular formula and connectivity but differ in the three-dimensional arrangement of their atoms. This type of isomerism includes both geometrical isomers and optical isomers....

A pair of orbiting black holes millions of times the Sun’s mass perform a hypnotic dance in this NASA visualization. The movie traces how the black holes distort and redirect light emanating from the...
