The wave model of the electron can be used to explain the Bohr model. Electrons are found in certain orbits because they interfere with themselves and create standing waves. When the wavelengths don't match up with a whole integer they...

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...

This video discusses the properties that all waves have in common, including amplitude and wavelength. It also demonstrates how to calculate the speed of a wave using the equation v = Fλ, where v is the wave speed, F is the frequency in...

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...

This video is a lecture presentation on the topic of conservation of momentum in physics. It explains the principle of conservation of momentum and how it can be used in calculations. The video provides examples of collisions between...

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!

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...

This video explains how to conduct an experiment to determine the speed of a wave on a string. It shows the steps involved, such as setting up the string or wire, creating a wave on it, and adjusting the distance between the two ends to...

In this video, the topic of food security and its various factors affecting food supplies are discussed. The narrator explains that having enough food to feed a population, especially when population numbers are rising, is important for...

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...

As a food writer, and blogger, Kathleen Bauer prefers to write from first-hand experience. The idea for pasture to plate came after responding to an offer from a farmer to purchase half a pastured pig.

The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

Howcast - Learn about the top seven museums to visit on a trip to Tokyo in this Howcast travel video.

When the nucleus was discovered by Rutherford, it became clear the classical world was not reality, because according to classical electromagnetism, the electron should collapse to the proton. This problem was...

This video provides an introduction to the speed of sound in air and demonstrates several methods to measure or calculate it. It also presents equations to calculate the speed of sound based on the wavelength and frequency of a sound...

This video explores the characteristics of waves. It explains the speed of waves, how this value is calculated and the four basic interaction between waves. Other terminology includes: vibration, crest, trough, amplitude, wavelength,...

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 the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

This video discusses the importance of absorption spectroscopy. A brief idea about ultraviolet and visible spectroscopy is presented in the video. The video shows the light sources used for different regions of operations. The type of...

The pandemic has been a massive catalyst for change for brands. Ukonwa Ojo, Amazon Studios' CMO, looks at the tone brands should strike and how Amazon intends to navigate the streaming wars as lockdowns ease.

Wave Motion | Waves | Physics | FuseSchool All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in...
