This video provides a simple and concise explanation of how mirrors work. It covers the history of mirrors, from primitive stones to modern glass coated with a thin layer of metal. The video explains the concept of reflection and how...

In this video we cover:

- The three things that may happen when a wave hits the boundary between two mate
rials
- How to draw ray diagrams, including the angle of incidence, the normal, and the angle of...

This video examines the various uses of light and the role of different types of lenses in light refraction. The way in which eyeglasses, contact lenses, and binoculars manipulate light to allow us to see better is illustrated. Other...

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...

When a ray or beam is reflected from a surface, the angle of incidence is the angle between the incident, or approaching, ray and a line perpendicular to the surface at this point.

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...

By the end of this learning object, the student will be able to: Identify the concept and laws of light reflection.13536

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...

In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...

Pupil outcome: I can investigate how changing the angle of a mirror affects the angle of reflected light. Key learning points: - If you change the angle that light hits a surface, the angle of reflection will also change. - Mirrors are...

When light hits something, a number of things can happen: it can be reflected, refracted, diffracted or absorbed. But what does this mean? Physics - Waves - Learning Points. Manipulation of light is vital to our survival. Light waves...

This is a lecture presentation on the topic of reflection and refraction experiments. The presenter explains the key terms involved in the experiment and demonstrates how the changing angle of incidence affects the angles of reflection...

This video is a tutorial on how to conduct an experiment investigating the reflection and refraction of light using a glass block. The video goes over the steps required to set up the experiment and make measurements of the angle of...

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...

In this video, we learn about the science behind apparent sunrise and delayed sunset. We explore the phenomenon of refraction of light and its effects on the direction and speed of light as it passes through different mediums. Through a...

This is a video about the behavior of light and the concept of reflection. It covers the laws of reflection, types of mirrors, and the difference between specular and diffuse reflection.

Bright pillars of light... clouds of glowing dust... shimmering discs floating around the sun... signs of extraterrestrial activity, or is there a more rational and scientific explanation for this phenomenon?

Optical fibres can carry information using visible light and something called total internal reflection. It works by bouncing waves off the sides of a thin piece of plastic or glass until it emerges at the end. Total internal reflection...

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...

The video discusses the concept of reflection, including the difference between specular and diffused reflection and how light interacts with irregular surfaces. It also includes a quiz to test the viewer's knowledge.
