This video is chapter 3 in my series on special relativity, and it covers boosts, galilean transformations,...

In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...

The complete reflection of a light ray within a transparent material.

By the end of this learning object, the student will be able to: Summarize the main points related to the reflection and refraction of light.86740

By the end of this learning object, the student will be able to: Demonstrate light refraction and some related concepts.86717

A humorous look at the topology of curved space.

This video is a lecture on magnification, specifically how the height of an image produced by a lens can be compared to the height of the object. The video discusses the two types of lenses, concave and convex, and how they produce...

The video demonstrates how to investigate the refractive index of a material by measuring the angle of incidence and refraction of light as it passes through a block of glass. The narrator explains the concept of refraction and shows how...

The video explains the concept of refractive index and how it determines the bending of light as it crosses the boundary between two different media. The video also demonstrates how to calculate the refractive index of a material, angle...

This video provides an explanation of the phenomenon of total internal reflection, which occurs when a wave travels from one material to another and is reflected back instead of refracting. The video also explains how to calculate the...

The video discusses the different ways in which waves behave when they encounter a boundary between two materials. The behavior can either be reflection, absorption, or transmission or a combination of the three. The video also explains...

Afterschool Universe is an out-of-school-time astronomy program for middle school students that explores basic astronomy concepts through engaging hands-on activities and then takes participants on a journey through the Universe...

This is a lecture video explaining the concepts of specular and diffuse reflection. The video discusses how light rays follow the law of reflection, where the angle of incidence is always equal to the angle of reflection. It gives...

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...

Through live action footage and animated diagrams students will come to understand that refraction is the bending of light rays when they go from one medium to another medium of different density. The program explains why light refracts...
