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...

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.

The video is a lecture on refraction and ray diagrams. It explains how ray diagrams can be used to describe the refraction of waves at the boundary between two different media, such as air and glass. The video covers concepts such as the...

Why can you see your reflection in some objects? In this video we will look at ray diagrams for reflection, refraction and colour absorption. Visible light is part of the electromagnetic spectrum. Light is a transverse wave, and travels...

This is a lecture video that explains how ray diagrams can be used to describe the reflection of a wave from a surface. The video begins by demonstrating how to draw an incident ray and a normal on a surface, and how to use the law of...
