Dubbed Ariel, the spacecraft is expected to launch in 2029 on ESA’s new Ariane 6 rocket.

Observatories including NASA’s Hubble Space Telescope found that the interstellar object named ‘Oumuamua gained an extra boost of speed, which likely comes from comet-like jets of gas.Credit: NASA’s Goddard Space Flight...

👉 Learn the basics to graphing sine and cosine functions. The sine graph is a sinusiodal graph with x-intercepts at x = 2n*pi, maximun value of 1 at x = pi/2 + 2n*pi and minimum value of -1 at x = -pi/2 + 2n*pi. The cosine graph is a...

This video explains the benefits of Blu-ray discs compared to CDs and DVDs. Blu-ray discs can store up to six times more data, thanks to the use of a blue laser beam that writes smaller. This allows for higher quality HD movies and...

Landsat satellites circle the globe every 99 minutes, collecting data about the land surfaces passing underneath. After 16 days, the Landsat satellite has passed over every spot on the globe, and recorded data in 11 different...

The video discusses the Doppler effect, which is the apparent change in the wavelength of a wave when the source of the wave moves relative to the observer. The narrator explains how the Doppler effect can be observed in everyday life...

Introductory video to the hydrogen line spectrum, which in part led to the initial development of quantum mechanics.<br/>

The GLAST mission launched on June 11, 2008 and has been returning remarkable and revolutionary discoveries ever since. Recently renamed to the Fermi Space Telescope, after Nobel Prize winner Enrico Fermi, the mission is expected to...

Lesson 17 (Waves, Light, and Sound) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need a review of AP Physics concepts before the exam? This course is for you! Exercises...

This video is a lecture on the effects of wavelength and speed on electromagnetic waves. The speaker explains what can happen to a wave at the boundary between two media, including reflection and refraction. They also discuss how...

We don't have to know too much physics to do chemistry, but the electron, the particle that makes all the chemistry happen, is a quantum mechanical particle, so we have to understand it just a little bit. Don't worry, no math, just...

NASA is about to launch the agency's most advanced laser instrument of its kind into space. The Ice, Cloud and land Elevation Satellite-2, or ICESat-2, will provide critical observations of how ice sheets, glaciers and sea...

With the Bohr model we start to get a better sense of the nature of matter, particularly the way light interacts with atomic matter such that we can see it. But how do we do calculations regarding these interactions? Let's practice now!

ICESat-2 is an incredibly precise space laser that features the latest in NASA technology To measure ice heights, engineers have to take ICESat-2's instrument ATLAS to the extreme - sometimes going big, sometimes...

The Doppler Effect is demonstrated. Animations are used to show the observed change in wavelength and frequency.

This video discusses the relationship between the temperature of a body and the rate at which it emits and absorbs electromagnetic radiation, particularly infrared radiation. The video explains how the relative rates of emission and...

Waves transfer energy from one place to another. You should already know how to describe them in terms of frequency, wavelength and amplitude In this video we’re going to look at the two ways they can be classified. Waves are produced as...

Resonance Fluorescence: A Special Case of Fluorescence

This is the winning entry for the 2014 Flame Challenge put on by Alan Alda and the Center for Communicating Science.

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...

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, well look at the fourier transform from a slightly different perspective than normal, and see how it can be used to estimate functions.

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...

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...
