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...

It explains two types of spherical lenses; convex and concave lenses. It also explains technical terms related to them.It also describes the converging property of convex lens and diverging property of concave lens.

In late June 2013, an exceptional binary system containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system...

Up until a couple centuries ago, we had no idea what light is. It seems like magic, no? But there is no magic in this world, really. Just stuff we don't understand. So let's understand light a little better right now!

In this lesson, students will learn how to identify and classify geometric figures in two-dimensional shapes. They will understand the properties of points, lines, rays, and angles and use them to analyze shapes. By recognizing parallel...

Measure angles.

Identify points, line segments, rays and lines in two-dimensional figures.

Measure angles in whole-number degrees using a protractor.

This video is a lesson on reflection in spherical mirrors, using everyday objects like spoons to explain the concepts. The teacher covers technical terms such as center of curvature, radius of curvature, and focal length, and explains...

X-Rays are part of the electromagnetic spectrum and have a wavelength of about the diameter of an atom. Because of this small wavelength they are able to penetrate healthy tissue but are absorbed by denser material like bone and metal....

It explains the discovery of protons and neutrons and their characteristics.

It explains the discovery of electrons by using the cathode ray discharge tube and the e/m ratio. It also shows how to find the charge of electrons.

In this lecture video, the different types of electromagnetic waves are examined, and their uses and applications are explored. The video begins with an overview of the electromagnetic spectrum, starting with gamma rays and ending with...

Using real world demonstrations and colorful graphics, Real World Science: Light teaches students the different properties of light, pertinent definitions and how light travels. Students will learn how different mediums can affect light,...

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...

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.

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.

Exploring the mysteries of dark energy and black holes. Identifying exoplanets. Capturing the origins of galaxies. Just some of what's happening at ground-based observatories -- windows on the universe that allow researchers to gaze...

An overview of the types of angles and their relationships.

So, what causes mutations? Well, this is where science fiction meets science fact, sort of. In the backstory of many superheroes there will be a meeting with a radioactive substance - be it cosmic rays or radioactive waste. In real life,...

In this video, we explore the groundbreaking discoveries of JJ Thompson and his plum pudding model of the atom. Thompson's experiments with electric currents and magnetic charges led him to hypothesize the existence of negatively charged...

Students will learn about the different frequencies along the electromagnetic spectrum. Vivid animation is used to explore the visible spectrum of light and the colors it allows us to see everyday. The video also investigates various...

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...

In this video, we explore how to classify and draw different types of angles. We start by understanding the properties of angles and how they relate to geometric figures. We review right angles, acute angles, and obtuse angles, comparing...
