The need to see in the dark; to observe weather patterns from outer space; or to conduct security surveillance at night, lead to the Big Idea of Night Vision, and Thermal Imaging. FLIR, or Forward Looking Infra Red, is a continuation of...

The Spitzer Space Telescope is one of NASA s four orbiting telescopes each observing in differing areas of the spectrum. Spitzer detects images in the infrared region, which shows activity not evident in the visible wavelengths.

Dive into the fascinating history of portable music players and the technological advances in remote controls. From the revolutionary Walkman of the late 1970s to the intricacies of cassette mechanics and the progression from infrared...

Mobile devices connect to other devices via wired or wireless. Wired connections are used for power and data transfer. Wireless options include NFC, Bluetooth, infrared, or 80 2.11 (Wi-Fi). These connections are used for a variety of...

If only we were all given a window so a doctor could look inside us when we were ill.Think of the operations that would save! Luckily there are now many ways we can see what is happening deep inside our bodies by using electromagnetic...

This video discusses the introduction of electric cars and the challenges faced in enforcing traffic rules, particularly regarding carpool lanes. It highlights a new infrared system that can accurately identify single occupant vehicles...

In this video we cover the following:

- The 7 different types, and order, of the waves in the electromagnetic spe
ctrum
- The phrase ROYGBIV to help you remember the order of colours in the visible ligh
t spectrum
- The...

Optocoupler. In this video we learn how optocouplers work and also look at some simple electron circuits you can make yourself to understand how an optocoupler, opto-isolator, phototransistor, photocoupler works. Photo transistor...

A black body is a theoretical or imaginary object that perfectly absorbs all incoming electromagnetic radiation, and also emits radiation, like heat and visible light, based on its temperature. A black body is considered theoretical...

This video will explain the electromagnetic radiation spectrum, what it is, and how it can be used to observe space objects.

There were never any planes in danger and I can prove it with science. First of all, we never turned the beam on more than 4 amps (50 watts)because we were having cooling issues and couldn't really monitor it up on the car.. (we tried 6...

Greenhouse phenomenon

In this video, we explore the theory, use, and parameters with infrared (IR) light therapy, a sub-type of thermotherapy with a different mechanism.

Learn the basics about the natural greenhouse effect. The atmosphere helps to keep our planet warm by making it harder for the energy we get from the sun to escape back to the universe. Our atmosphere is held to the earth by the force of...

Students will learn about the different frequencies along the electromagnetic spectrum. Vivid animation is used to explore the visible spectrum of light and the colors it allows us to see everyday. The video also investigates various...

In this video, we explore the theory, use, and parameters with infrared (IR) light therapy, a sub-type of thermotherapy with a different mechanism.

The video discusses the greenhouse effect and how it works in the Earth's atmosphere. It explains how greenhouse gases such as carbon dioxide and methane absorb long-wavelength infrared and re-emit it, increasing the temperature of the...
