Electromagnetic Spectrum
Fun Facts
- Astronomers rely on the electromagnetic spectrum to detect and visualize objects and events in space.
- Laser light can range from infrared to visible to ultraviolet on the electromagnetic spectrum.
- Radio waves, visible light, and x-rays are not different kinds of radiation but rather all parts of a continuous electromagnetic spectrum.
Why Do We Need To Know About Electromagnetic Spectrum
Studying the electromagnetic spectrum helps us see how the world works and how technology and nature are linked. Things like seeing, talking, and cooking are all affected by electromagnetic waves, which include radio waves and X-rays. Different parts of the spectrum can be used for encoding signals over WiFi networks and treating cancerous tumors.
Knowing about this not only makes us understand daily life better but also shows us many job options. People like doctors who work with X-rays, scientists who study stars, and firefighters use electromagnetic waves in their jobs.
