In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

Another little dancie dance for you to learn babeh! Today we work on a contemporary dance suitable for all levels of dancers, with some ooey gooey movement and allll the feelings. Hope you enjoy! Don't forget to post a clip of you doing...

What are isonitriles good for? The Passerini reaction! This is a very neat multi-component reaction that is good for generating chemical libraries. When was it invented? What's the mechanism? What are we doing with it today? Let's find out!

En este video aprenderás qué es el código postal o zip code y para qué sirve el código postal.

This is a lecture video on the topic of wavelength and color. The video focuses on the visible light portion of the electromagnetic spectrum, which can be split into different colors. The video explains the relationship between...

The video explains the concept of redshift and blueshift in the context of galaxy movement and how it relates to the shift in wavelength of light emitted by a galaxy. The video then shows how to use an equation to calculate the shift in...

The heights of a dual gravity drained tank are solved with the Scipy.integrate function ODEINT. This example demonstrates how to solve the differential equation and plot the solution.

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 is a video of DALF C2 speaking test in exam condition with a candidate and two examiners. This video presents the three parts of DALF C2 oral production: followed monologue: presentation of the document (1st part), followed...

Award Winning Short Film. Learn how the body and brain function, observe how we can dispel the stigma of mental health and see how your mental health impacts a community. This highly sensitive suicide prevention film contrasts how...

A quick demonstration of gravity and motion in this experiment with raw eggs before we cook them for breakfast. All we needed was: a toilet paper tube, a paper plate, a glass of water and a bit of curiosity.

Learn some German vocabulary while Herr Antrim recalls his favorite April Fools' Day jokes of all time. <b<b<b<b<b<b<b<b<b<b<b<b<br/>r/>r/>r/>r/>r/>r/>r/>r/>r/>r/>r/>r/>

The video is a lecture that explains the two features of a wave, namely wavelength and amplitude. It starts with a demonstration of a transverse wave and illustrates how the wave propagates while oscillating. The peaks and troughs of the...

Four mechanical wave graphs are introduced and used to understand and demonstrate transverse waves, longitudinal waves, wavelength, and period.

👉 Learn how to identify angles from a figure. This video explains how to solve problems using angle relationships between parallel lines and transversal. We'll determine the solution given, corresponding, alternate interior and exterior....

In this video Paul Andersen explains how the wavelength of a standing wave is determined by the boundary length and frequency of the wave. The fundamental frequency has a wavelength double the boundary length. Harmonics are built on...

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...

In order to understand how we study the universe, we need to talk a little bit about light. Light is a form of energy. Its wavelength tells us its energy and color. Spectroscopy allows us to analyze those colors and determine an object’s...

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from?

According to legend, the renowned scholar Jalaluddin Muhammad Rumi was giving a lecture when a disheveled man approached and asked him the meaning of his academic books. Rumi didn’t know it yet, but this question and this man would...

Hank's news this week informs us on a couple of crazy science experiments, updates us on some earlier topics (dangerous asteroids and ancient phallic rock art), and briefs us on a new study that seeks to find the evolutionary origins of...

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...
