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...

When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?

How do you begin to model the climate?

This is a lecture video that explains what can happen to a wave as it encounters the boundary between two different media. The video discusses the changes in wave speed and wavelength at the boundary, as well as the phenomenon of...

Wave Equation | Waves | Physics | FuseSchool Waves have a frequency (the number of complete waves passing a point every second and measured in Hertz), wavelength (the distance between two consecutive points on a wave) and amplitude - the...

Particle-on-a-Ring Example #2: Calculate Energy, Wavelength, and Momentum

This video provides an overview of The Big Bang Theory, which is a theory about the evolution of the universe. The narrator explains how the redshift of light emitted by galaxies that are moving away from Earth provides evidence for the...

A feature from NASA's Ames Research Center in Silicon Valley originally posted on May 23, 2017.

In this video, we use the following equations to interconvert between and do calculations with Frequency (λ), Wavelength (𝝂), & Energy: 1) E=h𝝂 2) 𝝂=c/λ 3) E=hc/λ

This video explores the concept of color illusions and how our eyes perceive and process different shades. It discusses the role of rods and cones in our eyes, the visible light spectrum, and the influence of background objects and...

Behind those stunning NASA images are specialized detectors developed, fabricated, and packaged here at the Goddard Space Flight Center. Tour the Detector Development Lab (DDL) and see how these first-of-a-kind detectors are...

In this video, the Debroy Hypothesis is explored, shedding light on the wave-particle duality of matter and the equation used to determine particle wavelength. The discussion delves into interpreting the hypothesis precisely, leading to...

This video is a lecture that explains the relationships between wave speed, wavelength, and frequency of a wave. It starts by defining a transverse wave and discussing the amplitude, wavelength, frequency, and time period of a wave. The...

Since the early 1990's, astronomers have known that extrasolar planets, or "exoplanets," orbit stars light-years beyond our own solar system. Although most exoplanets are too distant to be directly imaged, detailed studies have been...

NASA Goddard is preparing to demonstrate for the fist time in space, a 3-wavelength, laser remote sensing instrument. The Cloud-Aerosol Transport System or CATS will measure clouds and aerosols in the Earth's atmosphere. This...

NASA’s Nancy Grace Roman Space Telescope will be able to explore even more cosmic questions, thanks to a new near-infrared filter. The upgrade will allow the observatory to see longer wavelengths of light, opening...

Introduction to Fluorescence

In this video, you will learn how rainbows are formed through the behavior of light waves. Sunlight, composed of different wavelengths, enters raindrops, causing the light to split into a multitude of colors. As the light refracts and...

On July 18, 2012, a fairly small explosion of light burst off the lower right limb of the sun. Such flares often come with an associated eruption of solar material, known as a coronal mass ejection or CME -- but this one did not....

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface.



Temperatures in the corona — the...

This video covers natural and artificial sources of light, including topics such as bioluminescence, the visible spectrum, and the use of different wavelengths of light for various purposes such as heat therapy and currency detection....

On April 10, a team of international scientists from Event Horizon Telescope project unveiled the first ever image of a black hole at the center of the M87* galaxy. We invited computer scientist Dr. Katie Bouman and astronomer Dr....
