Learn about the electromagnetic spectrum, the order of the waves, their uses and dangers with this guide for KS3 physics students aged 11-14 from BBC Bitesize.
During this lesson, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different applications. This engineering curriculum aligns to Next Generation Science Standards (NGSS).

This article is about the Electromagnetic energy and its uses. It explains how electromagnetic energy travels in waves, spans a broad spectrum from radio waves to gamma rays, and how NASA's scientific instruments use it to study the Earth, solar system and universe beyond. The article also mentions that our atmosphere protects us from exposure to h...
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. When you tune your radio, watch TV, send a text message, or pop popcorn in a microwave oven, you are using electromagnetic energy. You depend on this energy every hour of every day. Without it, the world you know could not exist.
The Earth's atmosphere protects us from exposure to harmful higher-energy waves that can be ionizing and cause damage to cells in organic matter but is not helpful when studying sources of high-energy radiation in space as instruments have to be positioned above Earth's atmosphere.
NASAspacecraft provide scientists with a unique vantage point helping them "see" at higher-energy wavelengths that are blocked by the Earth's protective atmosphere while some microwaves can even pass through clouds making them best for transmitting satellite communication signals.
Radio Waves and Electromagnetic Fields. This simulation demonstrates wave propagation. The EM wave is propagated from the broadcast tower on the left, just as in Figure 15.2. You can make the wave yourself or allow the animation to send it. When the wave reaches the antenna on the right, it causes an oscillating current.
After lots of studying, YouTube videos, and help from my physics teacher friends, I finally realized that the only way for the EM spectrum to make sense for me is to think of it in terms of chemistry, not physics. I can understand it from the perspective of ionizing and non-ionizing energy. Most students know that atoms gain energy (and vibrate ...

Jan 3, 2023 · heating coil. matches. piece of flat metal or white paper. Set the mirrors around 4 feet apart, with the heating coil placed at the focal point of one of the mirrors. Try placing the piece of metal/paper into the path of the radiation. This will show your students how light is being reflected off of the first mirror.
