In this video Paul Andersen explains how ray diagrams for lenses can be used to determine the size and location of a refracted image. Images may be either real or virtual images. Ray diagrams for converging and diverging lenses are...

LIGHT! Let's talk about it today. Sunlight, moonlight, torchlight, and flashlight. They all come from different places, but they’re the very same thing: light! It’s what makes it possible for us to see the world around us, so it’s worth...

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.

How do lenses work? How do they form images? Well, in order to understand how optics work, we have to understand the physics of light. In this episode of Crash Course Physics, Shini talks to us about optical instruments and how they make...

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...

This video covers - The difference between convex and concave lenses - What 'principal focus' and 'focal length' are - The difference between real and virtual images Exam board specific info: AQA - Separate science only IGCSE Edexcel -...

The video is about using radar diagrams (also known as ray diagrams) to investigate how the type of lens used and the distance between the lens and object affect the formation of an image. The video shows four different ray diagrams,...

This video explains the concepts of myopia and hyperopia and how they can be corrected using concave and convex lenses. It also provides a simulation tool to help students understand the focal length, position, nature, and size of images...

This video is an educational lecture that explains the properties of concave lenses, how they form images, and the type of images they create. The video describes the definition of a lens and how it refracts light as it crosses the...

Physics Girl riddle: what happens to your image if you bend a spoon from concave to convex?

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...

The video is a lecture on convex lenses, explaining the way they work to bend and focus light. The speaker defines what a lens is, describes how convex lenses function, explains how to construct a ray diagram with a convex lens, and...

It explains the nature of images formed by different types of plane mirrors.

In this video the focus is on where and why concave mirrors are used, as well as the image formation and types of images. Students will learn that concave mirrors are used in many ways to magnify objects, create real and virtual images...

A diverging lens is sort of like the opposite of a converging lens because it curves inwards instead of outwards. It is represented with this symbol, interesting I know. Diverging lenses refract the light in a way, which makes them...

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...

Using animation and real world examples, this video explores the change in kinetic energy of particles with heating and cooling that produces expansion and contraction and change in density in matter. Students will observe and come to...
