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...

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,...

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...

Aperiomics, a small business funded by the National Science Foundation Small Business Innovation Research program, is developing a test that can identify a wide range of pathogens in one biological sample. Crystal Icenhour, CEO of...

👉 Learn how to simplify mathematics expressions. A mathematis expression is a finite combination of numbers and symbols formed following a set of operations or rules. To simplify a mathematics expression means to reduce the expression...

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.

Today we begin our discussion of computer graphics. So we ended last episode with the proliferation of command line (or text) interfaces, which sometimes used screens, but typically electronic typewriters or teletypes onto paper. But by...

Learn about the Other Non-Metals group of the Periodic Table with Non-Metals and Other Non-Metals Song Periodic Table by KLT.

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...

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...

Sunbeams shooting down through the clouds make for some great photographs, but what's the science behind these beautiful rays of light?

Some of the most exciting phenomena in space can’t be seen from Earth because our atmosphere soaks up high-energy light. That’s why NASA built Chandra, the most powerful X-ray telescope ever launched, and the observatory has helped...

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...

Some astronauts have reported the same specific symptoms: they see mysterious flashes of light out of the corner of their eyes. What causes those bizarre phenomena, and how does it affect astronauts?

The way light behaves can seem very counter intuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense! In this episode of Crash Course Physics, Shini shows us how we know...

The MainView is the central hub of any Twitter Clone app, and in this video, we will guide you through the process of designing and implementing a custom MainView that showcases all the essential elements of your app, including the feed,...

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...

This video covers:

- How to simplify more complicated ratios inclu
ding:
- Ratios with decimals in e.g.
1.5 : 4.5
- Ratios with mixed units e.
g. 1.6cm : 12mm
- Simplifying to the form 1:n e.g. simplify 3 : 2

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...

Why are so many airlines going under?

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....
