This video is answering the question of what is a radio frequency.

This video is answering the question of what are radio waves.

Importance of Radio examines the technology behind the common radio and breaks down the different types of wireless transmissions that modern radios use.

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

The video discusses the production of electromagnetic waves from atoms and nuclei. It covers different examples of producing radio waves, microwaves, x-rays, gamma rays, infrared radiation, visible light, and ultraviolet light. The video...

The undergraduate curriculum for physics and electrical engineering have some similarities that students may not be aware of. With both majors you get to see circuits, basics physics concepts, and even...

Lesson 18 (Electric Charge and Light) 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!...

We take lots of things for granted in this world; GPS, the internet and of course particle accelerators (well, maybe not particle accelerators!). However, none of these things would be possible without atomic clocks. In this video Dom...

This lecture video discusses the health risks associated with exposure to electromagnetic waves on the electromagnetic spectrum. The video covers different types of electromagnetic radiation, from microwaves to X-rays and gamma rays, and...

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...

What are the different wavelengths of the electromagnetic spectrum? When seen, what can invisible light reveal? What discovers has the VLA found so far? How do astronomers spend their time?<br/>

Do cell phones placed in a microwave still receive signals? What is the difference between microwave oven radiation and the signals used by your phone?

The sounds of Saturn, or rather the radio and plasma waves that Cassini picked up in Saturn's orbit.

Today, Tuesday, December 7, 2021, the U.S. Space Force’s Space Test Program Satellite-6 launched from Kennedy Space Center on Florida’s space coast. The spacecraft contains a revolutionary space communications mission, NASA's Laser...

Yes. Microwaves and radio waves are physically the same, i.e. both are forms of electromagnetic radiation. Some microwave rays can leak out and interfere with WiFi signals. We are basically constantly surrounded by electromagnetic...

NASA's Laser Communications Relay Demonstration Principal Investigator Dave Israel discusses the dynamic power of laser communications technologies.

Panelists Sheperd S. Doeleman, founding director of the Event Horizon Telescope (EHT), which produced the first image of a black hole, and Michael Johnson, astrophysicist, Harvard-Smithsonian Center for Astrophysics, answer questions...
