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...

A body scanner is a security device used in commercial airlines to detect metallic and non-metallic threats. There are two types of scanners, one using X-rays and the other using millimeter wave technology. Understand the differences...

This animated video is all about the Red Planet - Mars. Students will love this engaging and interactive video.

A secondary physics teacher uses role play to liven-up her KS4 lesson on radiation and smoke alarms, by dressing up as a radiation officer, in this engaging pedagogy video. She starts by asking her Year 10 pupils to consider how a smoke...

Learn about the different types of radiation in this physics video from the virtual school. Alpha particles, beta particles and gamma rays... what are they and how do they differ?



Introducing 'Alpha Man', 'Beta Boy' and 'The...

Can anything travel faster than the speed of light? Is it even possible for something to undertake the “speed of light” travel? And what if something can actually travel faster than light? What is Cherenkov radiation and how is it...

Chernobyl part 4/7: This video explores the construction of the world's largest land-based movable object, the arch that covers the Chernobyl nuclear reactor. It covers the challenges faced by the French engineering consortium that won...

A new report by a US National Academy of Sciences committee has found that “directed” microwave radiation is the likely cause of illnesses among American diplomats in Cuba and China.<br/>

Scientists say they’re finding clues that support a theory that the early moon and Earth’s magnetospheres combined <br/>

This video is about thermal radiation and how thermal energy is transferred by infrared radiation. The video also explains how different surfaces absorb and emit infrared radiation and their effect on the transfer of thermal energy. The...

The identity and chemical properties of any atom are determined by the number of protons in its nucleus. As atoms get bigger and heavier, the nuclei get bigger and heavier and the protons need a “nuclear glue” to help hold them together....

Underneath the surface of fearsome monsters we can see that Godzilla is closely linked to the fears of atomic radiation and mecha robots emerged from the extremely rapid industrialization of Japan during the 1960's and 1970's.

The space suit is a technological and engineering innovation that allows astronauts to exit the spacecraft while in outer space. Learn about all the different features of this machine.

Learn the key characteristics of comets, including their icy composition, the formation of their tails as they approach the sun, and their historical significance. The video also highlights the role of comets in bringing water and...

Alpha and beta particles are charged, whereas gamma radiation is neutral. Remember that opposite charges attract, so if you were to fire all three particles through an electric or magnetic field the alpha particles would deflect towards...

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...

This is a educational video that explains the concept of radioactivity in atoms. The video covers three types of radiation that are emitted by unstable atomic nuclei to become more stable - alpha particles, beta particles, and gamma...

In this video, the different forms of radioactive emissions are discussed, including alpha particles, beta particles, and gamma radiation. The potential uses of nuclear radiation in medicine and its potential hazards are also explored....

Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

The world's glaciers are shrinking at alarming rates, and many scientists believe it is due to changes in climate. Dr. Lonnie Thompson of Ohio State University and Dr. Douglas Hardy of UMass-Amherst discuss glaciers and how they...

"Uses of Nuclear Radiation What have the Hulk and Spiderman got in common? They both gained their super powers because of radiation. Well, in films and comics at least. In real life, radiation has never given anyone super powers. But...

Penetrating Properties of Radiation



Radioactivity. What is it? Should we b

It was Marie Curie who first used the word radioactive to describe a phenomenon discovered by Becquerel in 1896. It...

I was curious how bright a deadly dose of radiation would be after I watched Chernobyl. Hopefully this video helps you visualize what a dangerous dose of radiation would look like.

Sungrazing comets are a special class of comets that come very close to the sun at their nearest approach, a point called perihelion. To be considered a sungrazer, a comet needs to get within about 850,000 miles from the sun at...
