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,...

The video discusses the concept of light as a type of electromagnetic radiation and explains the different types of radiations in the electromagnetic spectrum based on their wavelength, frequency, and energy. It also highlights the...

2 min video describing the properties of waves for middle school science

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We are going to visualize the...

What is the purpose of light? How does light work? Why does Light exist? There had been a controversy about whether light was particles or waves. Albert Einstein showed that light must come in discrete packets of energy which today we...

Why does the universe have an upper speed limit on the speed of light? Why isn’t the top limit infinite? Or what if the speed of light was not constant but changed in different reference frames? The speed of light is dependent on two...

We deal with light on a daily basis, and it has wave-like characteristics that are essential to many natural and technological processes. The wave nature of light aids in the explanation of a number of important optical phenomena,...

The video explains how waves can be categorized according to two sets of criteria: transverse or longitudinal, and mechanical or electromagnetic. It gives examples of waves that fit each category, such as water waves as a transverse...

In this video Paul Andersen describes some of the properties of waves. He starts be identifying particles and waves as the only phenomenon that can transfer energy from place to place. He identifies the defining characteristics of waves;...

Electromagnetic waves are fundamental to understanding the nature of light and are oscillations of electric and magnetic fields that travel through space, carrying energy from one place to another. The spectrum of light is a small...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

The world appears to be a colourful place, but what are colours? What properties of light determine what colour we see? Physics - Waves - Learning Points. Colour is how our brains perceive different wavelengths of light. Newton...

After passing its last critical design review in February 2020, PACE has entered its integration and testing phase of development. PACE's primary sensor, the Ocean Color Instrument (OCI), is a highly advanced optical spectrometer that...

SUMMARY Why does the speed of light change in different media? or Does it? How photons always travel at the same speed, but the speed of light changes. In 1905 Einstein proposed the theory of special relativity. One of the postulates was...

The photoelectric effect is a phenomenon where electrons are emitted from a material, typically a metal, when exposed to light. This effect supports the quantum theory of light and demonstrates the particle-like properties of...

Polarisation is the process by which a transverse wave, such as a light wave is made to oscillate in one plane only. A Twig Science Glossary Film. Key scientific terms defined in just 60 seconds using stunning images and concise textual...

Frequency is the measurement of the total number of complete cycles or oscillations that a wave goes through in one second, and it is expressed in hertz (Hz). Frequency is a fundamental attribute that dictates the rate at which a wave...

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a God. But in the late 20th...

The video explains the basics of electromagnetic waves, including their definition as transverse waves that transfer energy from a source to an absorber. It discusses the seven general sections of the electromagnetic spectrum, going from...

Learn about the different types of waves, including transverse and longitudinal waves. Understand how these waves move through different mediums and their properties. Discover the speed of sound and how it varies depending on the medium....

Invisible to the naked eye, our night sky is scattered with the 100s of billions of galaxies the fill the known universe. Like the stars, these galaxies form constellations – hidden patterns that echo the reverberations of matter and...

In this video Paul Andersen explains the wave-particle duality discovered by scientists. In certain situations particles (like electrons and photons) display wave like properties. This phenomenon can best be explored using the double...

Niels Bohr, a Danish Physicist said “Everything we call real is made of things that cannot be regarded .” Is what we see perceived to be real or is it an illusion? In the world of our mind’s eye, light travels in a straight line. In...
